JavaScript Project Ideas for Beginners in 2024

Here are six amazing ideas for a project for JavaScript along with source code, that beginners can try to build knowledge and a portfolio.

  1. Single Page Application
  2. Clock
  3. Form Validation
  4. BMI Calculator

1. Single Page Application

single-page application

As a beginner, it’s recommended that you start with something simple yet interesting. Hence, single-page applications (SPAs) are a great option for applying your learnings and identifying your strengths and weaknesses. 

SPAs are web apps with a single page, limited features, and no refresh option. So, you create a web page that doesn’t reload every time you click on the side links but will change the content. Basically, one can load the functionality of website elements with a single click. Once it works well, you will gain confidence and motivation to advance your skills and build a more complicated project. 

One of the best examples of SPAs is Netflix, one of the most-used movie streaming apps. As you open it, you can explore many options and refresh multiple options with one click.

We all use clocks every day. We also know that time is precious and must be valued. People rely on alarm clocks and digital clocks to stick to their routines and ensure they follow schedules. So, why not create a digital clock using JS? It can be among the best JavaScript projects for beginners if executed well.

When you use a website or web application with a self-updating time element like clock, the chances are it is made using JavaScript. Hence, it is a useful project that will come in handy for JS projects, giving you insights into what you will be doing as a professional developer. 

The clock can include various features to make it interactive and fun, such as a timer, alarm clock, second/minute hands, stopwatch, etc. Pick this option to learn how to achieve specific project goals as a JavaScript developer.

BMI Calculator

Are you looking for JS mini projects as a beginner? Then, a BMI calculator is an excellent beginner-friendly idea. You create a simple calculator that asks for height and weight and returns the BMI value. 

It is a web application that calculates the Body Mass Index (BMI) of a user based on their height and weight. Fitness enthusiasts mostly use a BMI calculator to measure body fat and analyze their fitness levels by comparing their weight and height. 

Your BMI calculator app must be able to calculate BMI with one click, and users can see the result on the interface. Make sure to update the UI so that it provides relevant feedback related to BMI and include information regarding different BMI categories. 

It is powered by JavaScript and performs calculations based on user input. It is also capable of conducting mathematical calculations, managing user input, and changing the UI. To make the project more complex and sophisticated, you can include a few advanced features, such as personalized health advice according to the calculated BMI result, history log, and incorporation of additional health-related data. 

If you want, you can add a feature to build basic health-related web products to make it a more useful and effective tool.

The project will help you master more advanced concepts, including integration of backend services, data management, and user authentication. 

The app will make it easier for users to organize their activities and stick to their routines. It is also a learning experience where you will gain hands-on experience in DOM manipulation and even handling. 

Your project output is a unique app that allows users to list their tasks. As they edit, delete, and mark tasks, the UI automatically reflects the current state of the list. You can also add a login page so users can have a personal dashboard and to-do list. Once logged in, users simply have to create tasks, add multiple tasks, and save the list. 

Make it a user-centric app by providing interactive and friendly experience. It will help you brush up on your knowledge of web development principles and other important skills, such as local storage usage and event handling. Expand the app by adding cutting features like due dates, task prioritization, and categories.
