JavaScript is an open-source programming language designed for creating web-centric applications. It is lightweight and interpreted which makes it much faster than other languages and is integrated with HTML making it easier to implement in web applications.
In this Introduction to JavaScript article, you will learn all about JavaScript, the backbone of web development, and understand what exactly this language is and why and how this language is used across various fields.
JavaScript is critical for web development, and if you’ve ever thought about choosing that career path, you’d surely have come across this language. And probably, that’s why you are here in the first place.

JavaScript Output Methods and Properties
There are a total of six ways to display text and/or content with JavaScript, depending on where you want to write it to; the first three are properties, while the other three are methods:
The innerHTML, innerText and textContent properties written into an HTML element.
The document.write() method writes directly into the HTML output.
The window.alert() method displays an alert box, suitable for displaying error messages and the like.
The console.log() method writes to the browser console, making it ideal for displaying debugging information.
The rest of this programming tutorial will delve into each of these methods and properties.
