Learn How to Assess and Hire a Front-End Developer in 2020

The internet is a crowded yet indispensable marketplace. With over 1.7 billion websites and 3.5 billion daily searches on Google, it is challenging yet vital to have an online presence that provides you ample visibility. Also, the human mind has an attention span of five seconds, and one needs to create traction in this short period. The degree of exclusivity and the ability to engage with audiences is directly proportional to a website’s volume and revenue. An immaculate front-end development plays a crucial role in achieving the desired results.

Front-end development also called ‘‘client-side development,’’ is the art of creating an interface of the software, an app, a website, or any digital product. “Creating” refers to two elements – design and programming. The former comprises design, content, and just about everything else on the display screen, and the latter includes structure and behavior to put the design to use. The entire process, cumulatively, is termed as front-end development.

The visual appeal and aesthetics of the layout, the user-friendly design, responsiveness, interactive sections, efficiency, speed, and advanced functionality of the page, are all facets of front-end development. However, creating this requires a plethora of tools and the proficiency of a web developer who can convert data into an interactive interface. Thus, comes a front-end Developer. 

Right from development to delivery, website developers are responsible for developing user-facing code and the architecture of the website to provide an immersive user experience. To execute the desired objectives seamlessly, front-end developers are skilled in three core programming languages: HTML, CSS, and Javascript programming. In addition to fluency in these languages, they are also hands-on with various trending frameworks and libraries.

Now that you have a focused overview of a front-end developer’s work-regime, as a decision-maker, your next task is to find those who can meet your development needs. You can no longer afford to hire employees based on resumes and instincts in a digitally evolving world. You must have a clear understanding of must-have technical expertise and soft skills. Hence, we’ve created a clear pathway to enhance your hiring ability.

However, some confer that the talent of front-end developers cannot be corroborated in years. Some junior developers can possess all the skills needed for a project but lack experience. And vice-versa. Hence, evaluating your candidate begins with understanding the must-have requirements of your job profile. Before asking about what a front-end developer needs to know, you must update yourself with the core programming languages, new technologies, frameworks and libraries in the market to understand their knowledge and expertise.

Here’s What You Need to Know About the Tech Stack That’s Gaining Traction in 2020:

HTML:

The basic foundation of the World Wide Web – HTML has been building Web, mobile, and application pages for the longest time. 

• Its latest evolution HTML5, however, has been enabling developers to initiate some revolutionary creations with new syntactical features and a more massive stack of next-generation technologies.

• It is considered the Web’s default language, for it puts into perspective the outline created by HTML and CSS. 
• The entire dynamic and interactive behavior of software, like on-screen motion, immersive interaction, and appealing user-engagement, is because of this scripting language. 
• What makes it phenomenal is its extraordinary power of communicating with the server in the background with no interruption to the user interaction happening in the foreground, such as real-time updates without having to refresh or reload a page. 
• Major companies, including Microsoft, Netflix, Paypal, and Groupon, use Javascript to communicate and interact with their audiences. 
• According to individual reports, Javascript is the most in-demand skill in 2020, with over 10400 companies in the world using it.

These programming languages are the backbone of our digital products. However, as technology evolves, so does the process of creating software. Everything is becoming elementary to save on time, money, and resources with the creation of frameworks and libraries. This means one does not have to code from scratch or write codes repeatedly. Design, development, testing, and maintenance to foster a progressive process and to build increased interaction, developer communities and software companies are building frameworks and libraries that address challenges and add versatility when designing complex projects. But, the number of front-end frameworks and libraries is exhaustive. They keep appearing and disappearing, making it all the more indispensable to be updated. 

Here is a list of the top front-end technologies in 2020 that have earned a significant spot with their solid foundation and the ease with which they help create digital products. Their popularity and growth in the last year itself have been impressive and are expected to remain the same in the foreseeable future. 

React JS (Web + Mobile Development):

A core part of the present and the future of the front-end for any software is JavaScript library React JS. 

• Created and developed by Facebook and used by companies such as Instagram, Yahoo and BBC, among others, to build the best experience for their users.
• Though it is a relatively new player in the market, the library’s blazing speed has made it one of the most favorable JavaScript models for developers and the most critical resource in the JS tech stack.

The images mentioned above are self-explanatory. They are a true reflection of the importance of new frameworks dominating the market. Image 1 represents how, over the last year, AngularJS has gained global prominence in the tech world with its advantages. 

Conversely, Image2 depicts an exciting fact that nothing is ever constant. No one stack of technology can continually rule the market. So how do developers navigate amidst such varying leads and information? How can they keep themselves relevant without having to succumb to the rapidly changing landscape?

You need to look at the bigger picture and decide on your focus area if you are a front-end developer or aspiring to become one. Typically, a company requires you to possess a basic knowledge of the language with some design, UI skills, a strong foundation, and a relevant degree. This places you in the beginners or fresher category. But with an intensified competition, you must update and move into a more specific category. 

With a focused approach, keep a check on the tech stack to stay relevant, which involves understanding not just the languages, strategy and techniques but also their libraries and frameworks for a deeper skillset. 

Additionally, work on your soft skills, because ‘‘social distancing’’ or ‘‘solitary refinement’’ will be outdated soon.
