Java vs JavaScript

Many developers think that JavaScript and Java are the same language, but they are not. The difference between Java and JavaScript is like the difference between the earth and the sky. You don’t have to learn Java to learn JavaScript. Java is a programming language, but JavaScript is a scripting language. You can run JavaScript code in the browser, but you cannot run Java code in the browser. You need a compiler to compile Java code. Java is used to create OOP-based software, while JavaScript is used in web development. Java code is not dependent on any other language, while JavaScript code is dependent on HTML and CSS.
