What is JavaScript ?
JavaScript was initially created to “make web pages alive”.

JavaScript is an open and cross platform, dynamic computer programming language which is developed to implement complex features on web pages . It is a scripting language , which is used on both client and server side. JavaScript is the language of web development. Most interactions you have with websites, including buttons you click, forms you fill, and emails you send, are implemented with JavaScript.
Examples :
0 == false // true
0 === false // false, because they are of a different type
1 == "1" // true, automatic type conversion for value only
1 === "1" // false, because they are of a different type
null == undefined // true
null === undefined // false
'0' == false // true
'0' === false // false
