![]() ![]() Originally run on the client-side, the JavaScript implementation has branched out to the server-side after the Node.js development ‒ a cross-platform server environment built on the Google Chrome JavaScript V8 engine. Today, JavaScript has plenty of frameworks and libraries to simplify complex projects, such as AngularJS, jQuery, and ReactJS. The latter even started developing the first modern JavaScript engine, called V8, which compiles bytecode into native machine code. JavaScript has continued to grow alongside new browsers like Mozilla Firefox and Google Chrome since then. It was a general-purpose scripting language to ensure web pages’ interoperability across different browsers and devices. After Netscape submitted it to ECMA International as a standard specification for web browsers, JavaScript pioneered the release of ECMAScript. ![]() UI inconsistency: Sometimes JavaScript is interpreted differently by different browsers resulting in the inconsistent UI.The initial versions of the scripting language were for internal use only. Security: As JavaScript executes on the client side it can be used to exploit the application.Ģ. Server Load: As JavaScript executes on the client side it reduce the server load. JavaScript can be used in a wide variety of applications regardless of the file extension of web pages.Ĥ. Versatility: means having a wide variety of skills. Simplicity: JavaScript is relatively simple and easy to learn.ģ. Speed: JavaScript is very fast because it is executed on the client side.Ģ. ![]() ![]() Most of the latest browsers have JavaScript JIT-compilers and translator. But for later versions JavaScript code may be either interpreted or compiled using a JIT (just-in-time) compiler. Before Internet Explorer 8 and earlier, Firefox prior to 3.5 etc JavaScript was a purely interpreted language i.e. JavaScript is as interpreted programming language with optional JIT-compilation support. JavaScript is as object-oriented programming language.Ģ. It is developed by Netscape in 1995 and named as LiveScript which is later renamed to JavaScript. It is lightweight and commonly used to create interactive and dynamic web pages. JavaScript is the most popular programming language. ![]()
