INTRODUCTION CHAPTER - 1



JavaScript is a scripting language that has been developed to make web pages dynamic, interactive, and user-friendly.


   Javascript was first developed and launched by Netscape Communications Corp. in Netscape Navigator 2 beta (1995). There should be no confusion that Javascript is not the same as Java language (developed in the 1990s at Sun Microsystems).

Mocha -> Livescript -> javascript


JavaScript is an object-based language(Java is a fully object-oriented programming language). Javascript offers several built-in objects, and web developers can create or delete their own objects. Though javascript is not completely object-oriented prototypal inheritance makes JavaScript very different from other popular programming languages such as C++, C#, or Java which has features like classes and class inheritance In JavaScript, objects can inherit properties directly from each other, and this way it builds object prototype chains.



JavaScript is an interpreted language. That means, Javascript code is not compiled but directly executed by the interpreted. The interpreter software is inside the browser. One does not need to install any third-party software to execute JavaScript. In modern implementations, JavaScript code may be either interpreted or compiled using a just-in-time (JIT) compiler.
