JavaScript is a scripting or programming language that allows you to implement complex features on web pages — every time a web page does more than just sit there and display static information for you to look at — displaying timely content updates, interactive maps, animated 2D/3D graphics, scrolling video jukeboxes, etc.
JavaScript is commonly used for creating web pages. It allows us to add dynamic behavior to the webpage and add special effects to the webpage. On websites, it is mainly used for validation purposes. JavaScript helps us to execute complex actions and also enables the interaction of websites with visitors.
Once you really understand at a deep level how JavaScript works, you become quite capable of picking up other languages. Whether you're planning on eventually being a front-end or back-end developer, there's no doubt that JavaScript is the best coding language to learn for beginners.
