10 JavaScript Project Ideas for Beginners

JavaScript is one of the most important programming languages used in web development today. With the creation of frameworks like Express.js and Vue, it seems the language will continue to revolutionize web programming.

So if you’re a beginner, sit tight. These JavaScript project ideas will boost your skills and familiarize you with the basic concepts of the language.


1. A Simple To-Do List App

While building a to-do list using JavaScript, you’ll learn the basic logic behind CRUD actions. You’ll also explore the event handling functions of JavaScript. In this project, you’ll craft a script to create, read, update, and delete tasks.

Using event handlers, you’ll handle form submissions to enter each task, then display them after creation. Once the JavaScript code for controlling your app’s functionality works, you can use the CSS grid display method to organize each task. Then assign priority to them using the JavaScript conditional statement and date methods.

Although it’s not mandatory, you can take this further by saving tasks into a local database. For instance, storing each input in a JSON file on your local machine allows you to practice CRUD operations work on real-life JSON objects.

2. Create a Simple Timer

A timer is one of the easiest projects you can complete using JavaScript. Although it sounds pretty basic, it teaches you how to change the state of an element at timed intervals.

To add a bit of creativity, you can build a countdown timer that stops at a user-specified value. You don’t need to store anything in a database or JSON object, as this is an instance that users can tweak as they wish.

While coding the timer, you’ll familiarize yourself with JavaScript functions and time-bound events. You’ll also learn how to write JavaScript code for basic math conversions to handle different time parameters.

A carousel is one of the most visually appealing elements of a website’s UI. When coupled with great UX, it can make your website more user-friendly. Plus, it lets you manage space and display images or items in various layouts.

You’ll need to get your hands dirty with the JavaScript loop to build a responsive carousel. You can get your images from the DOM and push them into an empty JavaScript array. You’ll then add click events to a next and a previous button to display images successively, either to the right or the left.

That’s not the only approach, though. You can handle this task using any method that works best for you.

If you’re curious and want to go the extra mile, you can even animate your display to make it more compelling and easy to use.

4. Web Calculator

Building a responsive web calculator is another interesting JavaScript beginner project idea.

JavaScript, like other programming languages, supports numerous mathematical operations. So, while coding this project, you’ll learn how to use these operators dynamically. You’ll also add click events to custom HTML buttons or divs and learn how to organize your UI using CSS. That’s all it takes to build a responsive calculator that displays in the browser.

If you’re unfamiliar with JavaScript operators, you’ll get an opportunity to start playing around with them. You’ll then wrap your head around event handlers to better understand how they work.

While it’s more verbose, you can start by writing your script procedurally. But consider refactoring it into functions once your calculator starts working.

You can approach the design by creating a CSS flexbox. Then assign values and operators to the calculator buttons using HTML. Ultimately, you can call your event handling function on each element in the flexbox using a JavaScript loop.

5. Resume Generator With JavaScript

Although you might be a bit confused about how to start on this one, there are a couple of resume-building web apps out there to feed your idea.

Ultimately, you’ll make a reusable resume builder that can accept new information and drop or update existing ones.

Coming up with more resume templates isn’t difficult once you understand the basic logic. So, you can start with a single template and scale up to more catchy designs as time goes on. Of course, you also want to add a download button so users can get their resumes as PDFs.

A resume-building project helps you understand basic JavaScript CRUD operations. You’ll also learn how to use loops, event handlers, conditions, and some built-in functions. You can also save users’ information in a JSON object, so your program can reference it later.

6. Build a Browser Extension

Building a browser extension for a starter project might look complex. But it’s not once you understand the requirements for coding a functional one.

It’s a worthwhile task, especially if you already have a basic knowledge of JavaScript and want to try a more challenging project.

There’s a lot of effort involved in getting your extension to work across browsers. But you can start with a browser-specific extension and you don’t have to build a complex one. Yours can be a simple file downloader, an image resizer, or an extension to prevent certain content on Chrome.

While building your extension, you also need to make it installable. This is where you specify your app’s information in a “manifest.json” file so the browser can recognize and accept it. Overall, the project takes you further into solving real-life problems with JavaScript.

7. Build a Budgeting Application

We all want to monitor how we spend our money to avoid overshooting the budget. A budgeting app lets you track your expenses—so you don’t spend more than you bargained for.

Whether you build this for yourself or others, it’s a treasure worth stashing in your repository. Creating a DIY budget app with JavaScript doesn’t just improve your knowledge of DOM rendering. You’ll also learn to apply JavaScript operators to solve real-life problems.

While writing your code, you’ll collect form inputs and subtract expenses from your budget. You can take this further by writing code to set an auto-alert for the user whenever they’re about to overshoot their budget.

8. Unit Converter

Want to play around with basic mathematical operations and conditional statements in JavaScript? Creating a unit converter affords you that flexibility. It can be a length, weight, pressure, or temperature converter.

As well as writing mathematical formulas to convert units, you’ll learn how to tweak outputs and render them on the client side. Since your app will likely handle multiple conversions, you can create a dropdown where users can select their choice units.

Logical statements then handle how your script converts the parameters based on the user’s choice. Indeed, a unit converter is one of the easiest JavaScript projects you can tackle.

9. Create a Diary

Here’s a pretty handy JavaScript project for those who love to keep a tab on their daily routines. A diary app with JavaScript is a versatile but simple project suitable for beginners.

Because it’s a note-taking app, you’ll want to pin down dates according to activities. You can store these inputs in a file, as JSON objects, and reference them later when you need to track your history and saved inputs.

Although it might prove a little complex, you can save users from having to select activity times with code to store them automatically. Like a to-do app, this also teaches you how to build a CRUD application using JavaScript.

10. Brick Breaker Game

In case you didn’t know, you can also build a simple game using vanilla JavaScript. If you’re familiar with 2D games, you must have played or seen a breakout game before.

While it may require some foresight and thought, one of the positives of this project is the fun it brings in the end. Although it’s not a sure path into game development, you’ll learn about much of the functionality of JavaScript while working on this task.

Functionality is the goal. But you might need to combine some CSS with JavaScript here to arrange your bricks evenly. Ultimately, your program will dictate when a player wins or loses and what happens afterward.

JavaScript: Keep Learning by Doing

Taking on JavaScript projects is the best way to learn. These beginner project ideas will boost your skills and prepare you for real-life JavaScript projects.

That said, while styling is essential in most of these projects, be careful not to get distracted by it firsthand. Instead, focus more on the JavaScript functionality, and you’ll be building responsive websites before you know it. Happy coding!
