Originally a client-side language, JavaScript now powers both front-end and back-end development thanks to Node.js. With universal browser support, JavaScript projects have become indispensable for web development. Using it, developers can create everything from interactive forms and slideshows to full-scale applications.
Additionally, JavaScript’s syntax is beginner-friendly and ideal for those new to programming. Its vast ecosystem of libraries and frameworks includes React, Angular, and Vue. All this further extends JavaScript’s functionality to enable developers to build complex and responsive applications efficiently.
