What is JavaScript?
JavaScript, often abbreviated as JS, is a programming language that is one of the core technologies of the World Wide Web, alongside HTML and CSS. It allows you to implement complex features on web pages, such as creating dynamically updating content, controlling multimedia, or animating images. In other words, it makes web pages interactive.
While JavaScript is most well-known as the scripting language for web pages, developers can also use JavaScript to build web servers and develop the back-end infrastructure using e.g. Node.js.
In addition, there are numerous frameworks written in JavaScript that are an essential part of modern web development. They provide a collection of pre-written code so the programmers would not need to start from scratch. Examples of some of the well-known frameworks are React, Vue.js and Svelte.
Many people wonder why it is called JavaScript. When JavaScript was created, it initially had another name: LiveScript. But Java was very popular at that time, so it was decided that positioning a new language as a “younger brother” of Java would help. As it evolved, JavaScript became a fully independent language with its own specification called ECMAScript, and now it has no relation to Java at all.

JavaScript is a core competence of all our front-end developers. Either JavaScript or its extension TypeScript is used across all projects that involve web development.
