ES5 Vs ES6 : What is the Difference  \nLet's get Started  \nIntroduction to JavaScript:  \nJavaScript is a programming language that, together with HTML and CSS, is one of the core technologies of the World Wide Web. Over 97% of websites employ JavaScript on the client-side for web page behaviour, typically combining third-party libraries. When it comes to web development, JavaScript is one of the most popular languages owing to its features and capabilities.  \nThis article includes a JavaScript cheat sheet as well as rich JavaScript documentation and how-tos to make it easy for our readers to work with JavaScript. The purpose of the cheat sheet is to give you some quick, correct, and ready to use code snippets for common circumstances. In a nutshell, this article makes JavaScript simple for both novice and professional coders.  \nJavaScript Cheat Sheet  \nJavaScript Tutorial: Basics to Advanced Concepts  \n1. JavaScript Fundamentals  \n Writing JavaScript code in an HTML page: We must enclose the JavaScript code within the \u003Cscript> tag in order to include it on an HTML page just as the example shown below:  \n\u003Cscript type = \"text/javascript\">//JavaScript coding can be done inside this tag \u003C/script>  \nWith this information, the browser can correctly make out that the code is written in JavaScript and execute the code.  \n Inclusion of external JavaScript files in an HTML file: An external JavaScript file can also be written separately and included within our HTML file. That way, different types of code can be kept isolated from one another, resulting in better-organised files. For instance, if our JavaScript code is written in the file script.js, we can include it in our HTML file in the following way:  \n\u003Cscript src= \"script.js\">\u003C/script>  \n Usage of Comments in JavaScript coding: Comments are extremely useful in programming because they can assist others to understand what's going on in your code or they can help you if you have forgotten something. Keep in mind that they must be correctly identified so that the browser does not attempt to execute them. There are two alternatives available in JavaScript in which we can add comments:  \n Single-line comments: If you want to include a single line comment, start it with \"//\".  \n Multi-line comments: If you want to write a comment that spans multiple lines, you can wrap it in /* and */ to prevent it from being executed.  \n2. Javascript Variables  \nJavaScript Cheat Sheet  \nVariables in JavaScript are simply names of storage locations. In other words, they can be considered as stand-in values that we can use to perform various operations in our JavaScript codes. JavaScript allows the usage of variables in the following three ways:  \n var: The most commonly used variable in JavaScript is var. It can be redeclared and its value can be reassigned, but only inside the context of a function. When the JavaScript code is run, variables defined using var are moved to the top.
