JavaScript online coding tests aren't hard to create, There are almost 1.6 billion total websites in the world, and out of which 1.52 billion websites use JavaScript. That’s 95% of the total websites! It’s the true programming language of front-end engineering and the underlying language that ties everything together.
JavaScript is a runtime language for web browsers. This means when you open a web page, the page will load both the foundational JavaScript, which is standard with the page, and any new JavaScript added to a page. The new JavaScript will load in parallel with foundational JavaScript and can perform actions and make decisions.
According to a survey conducted by Stack Overflow, JavaScript has maintained its stronghold as the most commonly used programming language (eight years in a row!)
Skills JavaScript Developers must have:
JavaScript developers are responsible for ensuring UI/UX feasibility, optimizing applications, and implementing architecture and API designs. It is the responsibility of the developer to understand the need for a scripting language and frontend platform-related duties.
A good JavaScript Developer must be ready to perform in a fast-paced environment and implement complex design specifications in the least amount of time. So, besides having an in-depth understanding of JavaScript, an ideal candidate should have the following skills as well:
- HTML, CSS, and JavaScript: These will be needed to build dynamic websites or web applications.
- React, Angular, or Vue: These are part of JavaScript libraries and frameworks, and are used for building user interfaces.
- Knowledge of web markup, including HTML5 and CSS3.
- Proficiency with jQuery (“write less - do more” JS library) and Bootstrap frameworks.
