JavaScript was invented by Brendan Eich in 1995 and JavaScript code first ran in the Netscape browser. In 1996, JavaScript was introduced into the ECMA international standards organization and a technical committee (TC39) was formed to develop it. The standards for JavaScript are set by the ECMA organization and its official name is ECMA Script. The abbreviation of all versions of JavaScript starts with ES, like ES1, ES2, ES3 etc. The latest version of ECMA Script, version ES6, was launched in 2018.
JavaScript is one of the 3 main programming languages needed to create a website. Java Script is also a client side scripting language like HTML or CSS. This language is coded according to user behavior and incorporated into the website in which many functions are stored together. Like CSS language, Java Script can also be included in the webpage file in two ways, one is internal script Code and other is external script code file.
Internal JavaScript code is used in two ways in any webpage. First way, JavaScript functions can be used in any HTML element with the help of attributes and second, by using script tag we can write script code inside it. Additionally, JavaScript code executed in a webpage can be written in a separate JavaScript file, called an external JavaScript file. External JavaScript files are linked to the webpage they belong to.
