Why Use JavaScript For FrontEnd Development?

frontend-developers-long

JavaScript is a scripting language that is embedded directly in HTML code for browser interpretation. JavaScript can be read by a browser, interpreted, and then executed, thus creating powerful client-side experiences. Using JavaScript, you can check whether the user has entered a valid email address in a form field, and depending on which checkbox you select, you may receive a pop-up that asks for further information. In addition to HTML and CSS alone, it allows the site to perform additional functions.

Interactive websites

Many things can be accomplished with JavaScript on a website. One of its functions is to power the site’s overall interactivity. By using JavaScript, you can develop rich UI components such as image sliders, pop-ups, drop-down menus, form validations, tabs, and accordions.

By using HTML and CSS alone, the site is unable to accomplish additional functionality. By using JavaScript, webpages can respond to users’ activities and update themselves dynamically without requiring reloading the site.

AJAX Developer

Ajax

The AJAX acronym stands for Asynchronous JavaScript and XML. Web servers can interact with a webpage in the background without reloading the page.

Consider, for example, a webpage listing events. Event types are grouped by type and sorted by month by default. Changing the ‘ALL’ filter to ‘General’ initiates a background operation that partially reloads the page with our newly queried items. It doesn’t flicker when reloading, and we remain positioned exactly where we were, making browsing more enjoyable.

The AJAX protocol allows a webpage to send and receive data without requiring the user to reload the page, resulting in a seamless user experience.

Fixing Browser Specific Issues

Various web browsers are available: Firefox, Chrome, Safari, Opera, Edge … all of which run on different operating systems and devices. These browsers occasionally have their own bugs and quirks. It’s a fact of life that nothing is perfect. Even though W3C compliance standards continue to improve, frontend developers still need to use JavaScript to resolve issues.

It is possible, for instance, to write CSS styling rules that work perfectly in all browsers… except for Edge. This then leaves you with the option of rewriting the whole section or writing a workaround for the one browser you’ve chosen. In contrast, a JavaScript library like Modernizr can help isolate code for a specific browser. Utilizing the script you’ve written, along with some new style rules, you’ve resolved the problem.

What does a JavaScript Frontend Developer do?

User interfaces (UI) are created by frontend developers. An application’s user interface determines what each part of a site or application does and how it will look. The most rewarding and engaging task for me is crafting polished user interactions that delight and surprise users,” says Meta software engineer Mari Batilando. “This requires both attention to detail and a firm grasp of the platform.”

Frontend developers create the site’s layout for people who want to build a website. It is the frontend developer who determines where images should be placed, how the navigation should look, and how the site should be presented. Their primary responsibility is to ensure that the user can easily navigate and understand the design and layout of the site or application.

What does JavaScript Frontend code look like?

Object-oriented programming is the core of JavaScript 3 (the current iteration). JavaScript 3 is all about classes and objects, along with their attributes and methods. A car, for example, is an object in real life. Besides attributes such as weight and color, the car also has methods such as braking and driving.

In our example code we will use TensorFlow and Numpty which are JavaScript Frontend frameworks referenced from the JavaScript code. This means that a TensorFlow machine learning app is simply JavaScript program using the TensorFlow framework. The TensorFlow framework is used to create models and apply machine learning techniques in a scalable way.

Below we will write a JavaScript TensorFlow main training loop that solves the Nearest Neighbor problem in computer science.

import numpy as np
import tensorflow as tf
# Initialize the variables (i.e. assign their default value)
init = tf.global_variables_initializer()

# Start training
with tf.Session() as sess:

    # Run the initializer
    sess.run(init)

    # loop over test data
    for i in range(len(Xte)):
        # Get nearest neighbor
        nn_index = sess.run(pred, feed_dict={xtr: Xtr, xte: Xte[i, :]})
        # Get nearest neighbor class label and compare it to its true label
        print("Test", i, "Prediction:", np.argmax(Ytr[nn_index]), \
            "True Class:", np.argmax(Yte[i]))
        # Calculate accuracy
        if np.argmax(Ytr[nn_index]) == np.argmax(Yte[i]):
            accuracy += 1./len(Xte)
    print("Done!")
    print("Accuracy:", accuracy)

Interview Questions to ask your next JavaScript Frontend developer

Why do you like to program in JavaScript?

As a result, the candidate can share their JavaScript programming experience and thoughts on certain aspects of the language. Should code be written in an object-oriented or functional manner?

How do you ensure code quality?

Working on a JavaScript Frontend project requires quality control to ensure the end results are as expected. Check with the developer to see if the results are tested using any specific JavaScript development tools. Whenever engineers are working on JavaScript code, they must test for bugs and come up with ways to fix them.

What challenges have you faced in Frontend development? 

Answering this question will give you insight into their approach to Frontend problems. What are the most important things to keep in mind when writing Frontend code? Do they place a high value on efficiency? What is their structure for the problem? Is their solution good enough?

Team Work

Do you like to write code as part of a team? or do you prefer to write code alone?

This question can be answered in any way, so there is no right or wrong answer. If you are looking to hire an engineer, you may want to hire someone to work independently. On the other hand, you may be looking for a developer who is good at working with others and will fit seamlessly into an existing team .

Tell us about a coding problem you solved?

Using this question, candidates will be able to demonstrate their approach to solving problems. By doing so, they will demonstrate their ability to work under pressure and solve problems.

This does not necessarily relate to JavaScript coding, though it might. In some cases, the problem can also be related to teamwork. The employee could explain how he or she reached a consensus with a colleague concerning a specific problem.

By dealing with conflicts, they will demonstrate that they are able to work with others.

JavaScript Development History

Frameworks for JavaScript have evolved greatly, so any new developer must first learn a language before choosing a framework.

It has only been a relatively short time since some incredible innovations have resulted in the choice we have today. Gmail was Google’s first all-in-the-browser product, referred to today as Single Page Applications, as recently as 2004.

JavaScript is a good place to start, but there weren’t always so many options and flexibility if you wanted to do anything interesting with the browser.

AJAX

JavaScript was largely in its infancy in the early 2000s, and was primarily used to make basic changes to pages. Highlights included mouse-overs, dropdown menus, and scrolling text – things developers take for granted today thanks to CSS.

Through XML responses, Javascript was eventually able to communicate directly with the server. The two-way communication allowed developers to create real desktop-replacement applications on the web, which was unheard of at the time. In order to describe this newfound capability, AJAX was coined.

jQuery

Although jQuery was not technically the first JavaScript framework, its popularity skyrocketed when it was released in 2006. It abstracted much of the functionality developers wanted into a clean and easy-to-learn framework in order to solve many of the issues developers faced with subtle differences between web browser implementations.

Due to the ability to create web-based applications, developers built larger and larger solutions that tested jQuery’s maintainability. Despite the demonstrations of what could be achieved by products such as Gmail, it became apparent that enterprise-friendly tooling was needed.

Backbone & AngularJS

It was in 2010 that Jeremy Ashkenas released Backbone, the first framework aimed at developing single-page web applications. In an attempt to fix thousands of selectors and intertwined event handlers, Jeremy came up with a cleaner approach to jQuery applications. Although Backbone was an independent framework, it could be enhanced with jQuery if it was present.

AngularJS was created around the same time by Adam Abrons and Misko Hevery, and it soon fell under Google’s care after Hevery joined. First framework to provide a complete framework for building frontend applications, Angular. 

With AngularJS’s bi-directional data binding, you can bind a model’s data to HTML markup and see changes in real time. Reusable components and dependency injection were also supported by Angular.

React and Knockout

A similar framework, Knockout, also provides bi-directional data binding, although it offers fewer features than AngularJS.

React often becomes the framework of choice for new developers when they hear about it for the first time. Even so, React does have a steep learning curve, but it also has excellent documentation and a huge community to support it.

Nowadays, it has become increasingly important to consider how easily these frameworks support mobile devices. With NodeJS on the server side and JavaScript on the desktop and mobile browsers, along with additional frameworks using native devices, Ionic and React Native have proven influential players in standardizing JavaScript as a language for all platforms.

What do Frontend developers develop?

There are two sides to every web application or software program. On the Backend, the server logic and databases are present, while on the Frontend, the interface, navigation, and overall user interface is present. Developing the best web application requires the cooperation of these two sides.

One of the general responsibilities of a Frontend developer is to ensure that website visitors are able to interact with the page easily. A website’s appearance is coded through a combination of design, technology, and programming, and debugging is done as well. The Frontend developer is responsible for everything you see, click on, or otherwise do on a website

Application Types

The importance of code testing a JavaScript Frontend Developer

Code Test

The right candidates are found through code tests, along with other questions. However, to ensure that each test is effective, it must be customized to meet your specific requirements and skills that the developer must possess. As a result, it is critical that you know what you are looking for in a candidate before you begin the interview process. It is advisable to include both JavaScript and knowledge of the Frontend framework you’ve selected and web development expertise in general on the test if you’re looking to hire a JavaScript Frontend developer.

To identify the candidate’s strengths and weaknesses, we design the perfect coding assessment test that asks the right questions in the right format. At Hire JavaScript Developer, we test not only a candidate’s technical skills but also their soft skills.

How do you best manage the work of JavaScript Frontend Developers?

Typically, Frontend developers are supported by Backend developers within their teams. There is a need for effective management of this development team. It is also crucial to have a solid management structure in order to keep technical talent productive.

Defining key results will help you meet your business objectives

In order to align on measurable success criteria, product owners, development managers, and architects can define milestones and outcomes. After the leaders describe the objective, the team discusses, debates, and determines the key results.

Establishing OKRs regularly is a best practice. When OKRs are defined and measured too frequently, teams can lose sight of them. Two examples:

  • It may be necessary to reduce response times, app availability, or error rates in order to increase application reliability.
  • Using unit tests to improve deployment reliability 
How To Manage

Selecting the right development methodology

Agile methodologies are highly regarded by JavaScript Frontend developers. Determine whether the release schedule will be a sprint schedule or a release schedule.

An average one-week sprint is impossible for big user stories to be completed, but a two-week sprint allows for vacations and unexpected problems. Developers can ask for help when necessary during daily stand-up meetings to stay informed about what everyone is working on.

You need to be able to communicate

Good engineering managers connect their teams to the rest of the organisation and to customers. A JavaScript Frontend Developer must understand the company’s customers, target audience, and the rest of the team’s needs and constraints.

It is important to identify the needs of your target audience in order to develop software that will be both useful and profitable. Communication skills are essential for developers in order to work effectively with external teams and partners, as well as other internal teams.

We can help manage your remote team

As a software development company, we manage JavaScript Frontend developers and implement Agile methodologies. According to this view, people and exchanges are more important than procedures and devices, working software over detailed documentation, customer relationships over contract negotiations, and changing quickly over extensive planning.

Agile implementation goes beyond just adopting the methodology.  As a result of understanding your business and the way you work, we help you select the Agile methodology that is right for your organization. You can reduce time-to-market, increase productivity, and eliminate defects by choosing the right working methodology.

How to Manage

How long does a JavaScript Frontend Developer last in a job?

In the US, JavaScript Frontend Developers stay in their roles between 1.1 and 2.4 years after they are hired, with larger companies retaining workers for longer periods. Brazilian developers tend to stay in the same job for 1.6 and 3.7 years, respectively. It was traditional for people to stay with the same employer for their entire careers.

JavaScript Frontend developers frequently change jobs in search of new opportunities and higher salaries as long term loyalty has decreased over the years. As a result of the low unemployment rate and the need for mobile, cloud, and other essential technology skills, tech pros can easily move between jobs (or even start their own businesses). Communication is one of the most important components of our employee retention strategy.
