Programming Language: What Should JavaScript Developers Learn?

How do JavaScript developers enhance the performance of web applications?

Enterprises today are operating in the digital world and setting a new frontier of digital innovation. They are recreating a next-generation of business ecosystem by enhancing user experience and interfaces through smoother delivery of information on websites. However, these all are possible with the work of programmers and developers, including JavaScript developers. JavaScript is an object-oriented programming language used to build and control website content. Millions of webpages we see today are built on JavaScript.

This programming language is used beyond web browsing to the server-side. It allows developers to control and create, enhance and amend websites. A JavaScript developer implements the front-end logic that outlines the behavior of the visual elements of a web application. These developers often work alongside other front-end web developers specialized in mark-up and styling.

Programming languages are simply the formal languages that are used in computer programming to implement algorithms. And JavaScript leads these languages cohort. Alongside HTML and CSS, it is one of the core technologies of the World Wide Web, enabling interactive web pages and becoming an integral part of web applications.

As per SlashData's survey of developers, JavaScript remains the most popular programming language among developers, followed by Python and Java. It further revealed that JavaScript, which includes CoffeeScript and Microsoft's TypeScript in the survey, is by far the most popular language, with 12.4 million developers using it worldwide. Another report shows that JavaScript is used as a client-side programming language by 97.1 percent of all websites.

What Does a JavaScript Developer Do?

JavaScript developers are typically accountable for a website's programming, development and implementation. They work with websites, developing front-end applications and performing code analysis and overall improvement of style and usability. Along with this, a JavaScript developer requires to have a variety of skills such as collaboration, communication and technical writing. They know math, logic and abstraction with being detail-oriented and big-picture oriented. They are focused on the improvement and feasibility of UI and UX designs, enhancing the performance of the main front-end website, ensuring instant responses to user clicks, efficient data fetches from the server and dynamically updated pages.

What JavaScript Developers Should Consider?

JavaScript is a multi-paradigm programming language that supports event-driven, functional, and imperative programming styles. As it has the richest OSS module ecosystem available, JavaScript developers use this language to create interactive webpages, user experience, and responsive front-end design. However, to master this language, developers need to know about JavaScript classes, which are primarily syntactical sugar over JavaScript's existing prototype-based inheritance. Indeed, classes are special functions and a programmer can define function expressions and function declarations.

JavaScript programmers and developers must understand the amount of asynchronous code found in idiomatic JavaScript. Asynchronous code refers to code scheduled to run after some event, delay or response. It can be found in various ways in JavaScript code and essential to construe them. Developers have distinct personalities that make them different from others. They are investigative individuals, which mean they are intellectual, introspective, and inquisitive.

JavaScript programming language has an ecosystem of developer tools for identifying and diagnosing bugs, and analyzing application code. Learning these tools well will strengthen a developer's skills.

The popularity and demand for JavaScript developers are relentlessly escalating. Every type of business, whether it is large corporations, small and medium-sized companies or public bodies, capitalize on the knowledge and skills of JavaScript developers.
