You will learn all about JavaScript in this tutorial from basic to advance.
JavaScript is a client and server-side object-based scripting language that is used to make interactive Web pages. A scripting language is a lightweight programming language with less complexity.
JavaScript is the most usually used scripting language to add dynamism and interactivity to Web pages. This is because JavaScript, written on the client-side, executes on a client browser, thereby reducing the load on the server.
JavaScript is an interpreted language, which implies that scripts written to JavaScript are processed line by line. These scripts are interpreted by the JavaScript interpreted, which is a built-in component of the Web browser.
JavaScript can be written on the client-side as well server-side. Client-side JavaScript allows you to validate only those programs that execute and produce the result on the client-machine. In counterpoint/contrast, server-side JavaScript validates only those programs that execute on the server. JavaScript includes various built-in objects and features that can be used to make your HTML pages dynamic.
JavaScript is platform-independent, which implies that you need to write the script once and can run it on any platform or browser without affecting the output of the script.
