JavaScript has become the most popular programming language for web development in the last two decades. The fact that JavaScript is used by more than 94 percent of all websites, according to recent studies, demonstrates the importance of JavaScript as a web development language. Since part of our course is to work with frontend and backend, we work with a mix of JavaScript, HTML, and CSS. This blog will focus only on the importance of JavaScript for developers to build a frontend.
What is JavaScript?
JavaScript is a client-side programming language that enables web developers to create dynamic and interactive websites by allowing them to integrate bespoke client-side scripts. Developers can also develop server-side code in JavaScript using cross-platform runtime engines like Node.js. Combining JavaScript, HTML5, and CSS3 allows developers to create web pages that function across multiple browsers, platforms, and devices as already mentioned in the previous paragraph.
Many JavaScript frameworks, such as AngularJS, ReactJS, and NodeJS, are available on the web. Developers utilize JavaScript extensively to construct diverse web applications and add interactive elements to them. JavaScript is supported by the majority of online browsers, allowing dynamic content to be displayed beautifully on websites. WordPress is the most popular content management system (CMS) today, and JavaScript is used extensively in its development. A web developer who is well-versed in JavaScript may create a variety of applications that are both stable and scalable. If you want to be a professional WordPress developer, you’ll need to understand JavaScript so you can make informed decisions right away.
The role of a front-end web developer is to write the code and mark-up that a web browser renders when you visit a website
When it comes to front-end development, there are three key components: HTML, CSS, and JavaScript. Each is necessary for a webpage to function properly. HTML is responsible for the site’s structure and content, CSS is responsible for its aesthetics, and JavaScript is responsible for its interaction. When it comes to developing websites, they all operate together, but the focus of this blog post is on JavaScript and how it’s employed.
JavaScript is a versatile programming language that may be used to do a variety of tasks on a website. For starters, it is responsible for the site’s overall interactivity. Image sliders, pop-ups, site navigation mega menus, form validations, tabs, accordions, and other complex UI components are all feasible with JavaScript.
It can also perform more subtle operations. For example, you might click a checkbox on a form, and a pop-up appears asking you another question, depending on which checkbox you picked. It adds capabilities to the site that would otherwise be impossible to provide with just HTML and CSS. JavaScript enables websites to respond to user action and dynamically update their content without requiring a page reload.
For a front-end web developer, JavaScript is an essential tool. Websites would not have evolved into the dynamic web apps that they are today without it.
