How to add JavaScript to HTML in 2 Easy Steps

A solid foundation in computer programming is essential for a successful career as a web designer. You must also master key programming languages. JavaScript is one of these programming languages.
JavaScript is used to build some the most popular websites and apps in the world. This is why JavaScript-certified web developers are so in demand.
This article will demonstrate how to add JavaScript into HTML in just two steps. We’ll also discuss the basics of JavaScript and its many uses in the tech industry.
What is JavaScript?
JavaScript (or JS), is a scripting language that allows you to implement interactive and dynamic elements on web pages. JS can also be used to create web apps and browser game. It can be used for many applications, including servers, hardware controls and software.
JavaScript allows for interaction between the web browser and the website that the user is visiting. Every major web browser has a JavaScript engine that executes JS code on users’ computers.
JavaScript allows web developers to add dynamic and interactive elements and prevents web pages being static. JavaScript allows you to insert animation, audio, or video into your web pages (with play, stop, pause and play buttons), and automatically place the cursor in the search box for Google Search.
JavaScript, along with HTML and CSS are part of the three core technologies required to build websites. HTML, which stands for HyperText Markup Language, provides structure to web content. Examples include data tables and lists of bulleted point, as well as headings and data tables.
CSS (Cascading Style sheets) is a style and layout tool that applies to HTML content. You can set background colors and font colors, standardize spacing between elements and add background images.
Although JavaScript and JavaScript share similar syntaxes and standard libraries, the two programming languages are very different. Java is an OOP programming language, meaning it runs in a browser or virtual machine. JavaScript, on the other hand is an OOP scripting language that runs only in the browser.

What is JavaScript used for?
JavaScript can be used to create complex websites, browser games, apps, and other web applications. It can also be used to connect servers to websites or web apps. Many of the most widely-used websites and apps on the internet use JavaScript–including Facebook, Netflix, Google, and YouTube.
Many technologies have emerged in recent years to take advantage of JavaScript’s power. JS now offers a wide range of frameworks to help you build web and mobile apps.
Frameworks are a collection of pre-written JS codes. They work in the same way as blueprints and allow developers to create websites and apps with more functionality.
These are the most popular JS frameworks:
React is a tool that you can use to create user interfaces for web applications.
React Native is a tool that you can use for building mobile apps
Node.js allows two-way communication between servers for data exchange

JavaScript is required to make web pages interactive and dynamic. Developers can implement the following features by incorporating JS into their coding:
Keep your content current and relevant
Interactive maps
Drop-down and hamburger-style menus are possible
You can play audio and video
Zoom in and zoom out on images
Animation and 2D/3D graphics can be added
Carousel format for image galleries
Insert hover effects
Display and hide menus
Alert users to inconsistencies in passwords

JS can also be used to create complex in-browser gaming experiences. JS is used in many browser-based games, such as Angry Birds and Bejeweled.
Statista says JavaScript is still the most popular programming language among web developers due to its versatility and ease-of-use. Nearly 65% of JavaScript-using developers will use JavaScript by 2021. W3Techs reports that 98% of websites use JS to manage web page behavior.
How to add JavaScript to HTML
We’ve already discussed how HTML, CSS, JavaScript are necessary to create functional and dynamic web pages. You can think of your website like a three-layered cake: HTML is the foundation, CSS is the middle layer, and JavaScript is the top layer.
First, structure your content with HTML. Then add stylistic elements to the page and a proper layout using CSS. Next, you will need to add dynamic and interactive HTML functions.
There are two ways to add JavaScript HTML to HTML. The first is to embed JS code in HTML. The second requires that you create an external JS file.
1. HTML HTML Embed Inline JavaScript code
JS must be loaded and run with HTML markup when working with files for the Internet. This can be done inline within an HTML file. Click h
