JavaScript is a programming language that was created by Netscape in 1995. It allows for the development of interactive websites and web applications. JavaScript is used on millions of websites and is one of the most popular programming languages in the world. It is also a relatively easy language to learn, making it a popular choice for beginners.
JavaScript is a dynamic, interpreted language that uses closures, prototypes, and first-class functions. It is similar to Java but is much simpler and less verbose. JavaScript was originally designed as a client-side scripting language to be used in web browsers, but it can also be used on the server-side to create full-stack applications.
