Introduction

Welcome to JavaScript beginner tutorial series. In this article you will learn how to setup JavaScript on your machine. JavaScript is a high-level, interpreted programming language that is used to create interactive and dynamic web pages. It was initially developed by Brendan Eich at Netscape in 1995 and has since become one of the most widely used languages for web development. JavaScript can be used both on the client-side (in web browsers) and on the server-side (with the help of Node.js), making it a versatile language for building full-stack web applications. Some of the key features of JavaScript include its dynamic typing, first-class functions, and prototype-based object-oriented programming model. With its ease of use and broad range of applications, JavaScript has become an essential skill for developers working in the web development space.

In this article, we will guide you on how to set up Visual Studio Code for JavaScript coding on both Windows and Linux platforms. We will also show you how to write a simple “Hello World” program in JavaScript using Visual Studio Code.
