Hangman is a well-known game, and one of our simple JS projects. You can develop it in a jiffy using JavaScript, HTML, and CSS. Note that the main functionality is defined using JS. HTML is for display, and CSS does the job of beautifying the contents. 

Many methods are defined in the JS code, so it may seem a bit complicated, but you will realize it is simple once you read the code thoroughly. You can also run the code and see the execution line by line.

Check the code and execution here.

9. JavaScript Weather App

JavaScript Weather App

Weather apps are also popular JavaScript projects. Once you change the location name in this project, the weather display changes immediately without a page refresh. The UI is also quite sleek. 

Note that most weather apps use an API that gets the weather data. We will use the popular and most common API, OpenWeatherMap. 

Check out this Youtube video that explains the weather app code and functionality in detail. There are three files, as usual: index.html, main.js, and main.css. Although you can put all the code in a single file (HTML), it is more convenient to maintain separate files. 

10. Build a Shopping Cart for Order Fulfillment

How To Setup Your JavaScript Environment

Before you start coding in JavaScript, it's essential to have your coding environment properly set up and ready for action.

Being an interpreted language that runs in web browsers, you don't need to worry about having a compiler.

That said, setting up a good development environment can really help to enhance your coding efficiency and provide you with powerful tools to debug and test your code.

If you want to dive straight in, I'd recommend following along with me using our online JavaScript compiler. This is pre-populated with the HTML, CSS, and JavaScript files you need to build any JavaScript project without switching on an IDE.

Equally, if you're already equipped with a basic setup on your own computer, you might want to skip this.

If not, let me walk you through how to set up a JavaScript development environment. You can even use these steps for any of the most popular operating systems.

Install a JavaScript Code Editor

First things first, you'll need a code editor that supports JavaScript syntax highlighting and potentially IntelliSense for code completion.

Visual Studio Code (VSCode) is a popular choice among developers for its extensive feature set and vast library of extensions. That's why it's one of my favorite web development IDEs.

Assuming you have VSCode installed, follow these steps to enhance your JavaScript development experience:

Open VSCode and navigate to the VSCode Extensions tab (you can use the shortcut `Ctrl+Shift+X` on Windows/Linux or `Cmd+Shift+X` on macOS) and search for JavaScript-related extensions like:

  • ESLint for linting and maintaining code quality.
  • Prettier for code formatting.
  • JavaScript (ES6) code snippets for handy code snippets.

You can install these extensions by clicking the install button next to each.

Install a Web Browser with Developer Tools

Modern web browsers like Google Chrome, Mozilla Firefox, and Microsoft Edge come with built-in developer tools, which are indispensable for web development.

These tools allow you to debug JavaScript, inspect the DOM, view network requests, and much more.

Install Node.js and npm [Optional]

While JavaScript runs in the browser, Node.js allows you to run JavaScript on your computer as a standalone application, which is particularly useful for development. You can download Node from the official website.

I'd also recommend choosing the LTS (Long-Term Support) version for stability.

Next, we have npm (Node Package Manager), and luckily for you, this comes with Node.js! The more you dive into JS development, the more npm is essential for managing JavaScript libraries and packages.
  
After installation, I'd also recommend verifying that Node.js and npm are correctly installed by opening your terminal (Command Prompt, PowerShell, or Terminal app) and running the following commands:

node --version
npm --version

These commands should display the versions of Node.js and npm, respectively, indicating a successful installation.

If you're really new to coding, you might want to skip this step, but even then, I'd really recommend becoming familiar with Git as soon as you can.

If you want the TL-DR, Git is a version control system that lets you track changes in your code and collaborate with others.

While this step is not strictly necessary for JavaScript development, it's a best practice, especially for larger projects or when working in a team.

Simply download Git from the official Git website, and during installation, you can accept most default settings. That said, you might want to choose your preferred text editor and ensure that Git is added to your system's PATH.

Wrapping Up

And there we have it! If you've taken the time to build these 16 JavaScript projects, you should be feeling much more competent and confident with JavaScript.

You'll also have a burgeoning JavaScript portfolio that's packed full of interesting and practical JavaScript projects, each demonstrating your dedication and abilities.

I also hope you enjoyed following along with my step-by-step tutorials in the first seven JavaScript projects! Which one was your favorite? I'll confess that I really enjoyed making all of them, especially the drum kit!

My motivation with these JavaScript tutorials was to guide you through the nuances of JavaScript development while also giving you hands-on experience that you'd usually only get when taking a JavaScript course.

Here at hackr.io, we're huge fans of project-based learning, so I hope these JavaScript projects have bolstered your confidence and sparked a deeper interest in web development or any other form of JavaScript development.

Remember, the journey doesn't end here!

With new projects and step-by-step tutorials regularly added to this page, be sure to check back often for new opportunities to refine your JS skills and expand your portfolio.

And remember, you can do all this using our online JavaScript compiler, so get creative, have fun, and happy coding!
