JavaScript is a programming language that enables you to create dynamically updating content, control multimedia, animate images, and pretty much everything else. As a result, JavaScript is one of the three technologies used in most web development projects.

JavaScript can be used to create interactive websites, games, and applications. The language is also used in server-side programming, desktop applications, and mobile apps. In fact, JavaScript is now the most popular programming language in the world.

So, what can you do with JavaScript? Here are a few examples:

Create interactive websites

JavaScript is used to create interactive websites. For example, you can create menus that drop down when you hover over them, or form elements that change when you click on them.

Interactive websites are those that allow users to interact with the site in some way. This can be through clicking on links, filling out forms, or even playing games. JavaScript is often used to create these interactive features.

JavaScript is used to create dynamic content. This means that the content on the page can change without the page having to be reloaded. This is often used to display different content to different users, or to show different content depending on the time of day.

Animate elements on a web page

You can use JavaScript to animate elements on a web page. For example, you can create a button that fades in and out when you hover over it, or an image that slides up and down when you click on it.

Animations can add a touch of fun and interactivity to a website. They can also help to direct a user's attention to important elements on the page. JavaScript is often used to create animations, as it is a simple and effective way to do so.

Other methods of creating animations include using JavaScript to change the style properties of an element, or using a library or framework such as jQuery.

Create games

JavaScript can be used to create simple games. For example, you can create a game where you have to click on a target to score points. You can create a memory game where you have to match pairs of cards, or a puzzle where you have to move pieces around to solve it.

You can also create more complex games, such as ones with multiple levels, or ones that require you to use strategy to win. There are many possibilities when it comes to creating games with JavaScript.

There are many libraries and frameworks available that make it easier to create games with JavaScript. For example, Phaser is a popular framework that includes many features to help you create games. It includes a physics engine, so you can easily add features like gravity and collisions. It also has a lot of built-in graphics and sound assets that you can use in your games.

Create applications

JavaScript is a cross-platform language, which means that code written in JavaScript can run on different types of devices. This makes it possible to create applications that can be used on a wide range of devices, including smartphones, tablets, and laptops.

JavaScript is used to create applications that run in the browser. JavaScript code is executed by the browser, which means that it can run on any platform that supports a browser. JavaScript is a versatile language that can be used to create a wide variety of applications.

In addition to running in the browser, JavaScript can also be used to create applications that run outside the browser. For example, you can create a command-line application that allows you to manage your files and folders. This can be very useful for developers who want to automate tasks or create tools that they can use themselves or share with others.

Create mobile apps

JavaScript can be used to create mobile apps using frameworks such as React Native and Ionic. These frameworks allow developers to create cross-platform apps that can be run on both iOS and Android devices. JavaScript mobile apps can offer a native app-like experience to users and can be used to create a wide variety of apps, from simple games to complex business applications.

React Native is a popular framework for creating JavaScript mobile apps. It is used by developers to create cross-platform apps that can be run on both iOS and Android devices. React Native apps can offer a native app-like experience to users and can be used to create a wide variety of apps, from simple games to complex business applications.

Ionic is another popular framework for creating JavaScript mobile apps. Ionic apps can be used to create a wide variety of apps, from simple games to complex business applications. Ionic apps are created using HTML, CSS, and JavaScript, and can be run on both iOS and Android devices.

JavaScript is a versatile language that can be used to create a wide variety of applications. Whether you want to create a simple game or a complex application, JavaScript is a good choice.

Where to learn JavaScript?

You usually learn JavaScript with HTML and CSS.  Online coding bootcamp with front-end web development programs and full-stack web development programs is a good place to start!
