Top 15+ JavaScript Projects With Source Code (2024)

Introduction

JavaScript is one of the web’s most powerful and adaptable programming languages. It powers most websites’ dynamic behaviour. JavaScript is a lightweight object-oriented programming language that is used to script web pages by several websites. When applied to an HTML document, it is an interpreted, full-featured programming language that enables dynamic interactivity on websites. It was first released in 1995 to allow users to add programs to web pages in the Netscape Navigator browser.

Since then, all other graphical web browsers have embraced it. Users can use JavaScript to create modern web applications that interact immediately, without having to reload the page every time. JavaScript is used on a standard website to provide many sorts of interactivity and simplicity. Companies are continuously looking for experienced JavaScript Developers who can create unique GitHub JavaScript projects. Working on some real-time JavaScript projects is the best thing you can do if you’re a JavaScript programming newbie.

Let’s have a quick look at some features of JavaScript:

• Because it has built-in execution environments, all popular web browsers support JavaScript.
• The grammar and structure of JavaScript are based on the C programming language. As a result, it is classified as a structured programming language.
• JavaScript is an object-oriented programming language that inherits through prototypes rather than classes.
• It’s a simple and interpreted language.
• The language is case-sensitive.
• JavaScript is compatible with a variety of operating systems, including Windows, macOS, and Linux.
• It gives consumers complete control over their web browsers.

JavaScript Projects Ideas (2024)

Below are a few exciting JavaScript Projects to try. We have divided projects based on beginner, intermediate, and advanced levels.

JavaScript Projects for Beginners

1. JavaScript Calculator

Calculators are fun, so, to begin with, we will build a simple Calculator using JavaScript. We’ll utilize fundamental JavaScript functions to make all the components work, as well as simple HTML and CSS. We’ll use HTML to display buttons and numbers, and CSS to make them more appealing. Furthermore, we’ll utilize JavaScript to make the buttons do their jobs. 

The source code link of a simple JavaScript Calculator is given below-

2. Build a Clock using JavaScript

Who does not use a clock? It would be great if you could build a clock using JavaScript. There’s a good possibility you’re on a webpage or using a web application that has a self-updating time component (like a clock), and it’s powered by JavaScript code. This implies that JavaScript clocks aren’t just useful for creating JavaScript projects; they also allow you to practice the type of work you’ll be doing as a JavaScript developer. The source code of a very nice and interactive clock has been provided below for your reference.

6. Timer

Building a simple timer turns out to be more difficult than it appears. One would expect that displaying the proper time would be as simple as utilizing the same setInterval method as in the digital clock project. It turns out that the method doesn’t work in this case. We establish variables to hold various time-related information for this project, such as when the time began, when the time was stopped, and how long the time was paused. Our digital clock would simply be unable to display the time elapsed without these variables and the calculations we conduct with them.

So, what are you waiting for? Let’s build our timer using JavaScript. Ready, Set, Go.

10. JavaScript Form Validation

Many websites utilize form validation for client-side validation of user details, card details, address details, and other information. If a mandatory input field name exists, the user can type a number, leave the field blank, type only one letter, and so on. All of these validations are simple to implement using JavaScript. Let’s look at an example of a simple form validation project. HTML elements will be required as well, as is customary.

12. Whack-a-mole game

I think everyone has once in his lifetime played this game. A standard Whack-A-Mole machine has a waist-level cabinet with a play area and a display screen, as well as a huge, soft black mallet. Five holes in the top of the play area are stuffed with small plastic moles that appear at random. Whacking each mole as it appears earns you points. The higher the score, the faster the reaction. To create this game, one has to keep in mind these functions-

• A function that generates a random length of time for the mole to peep.
• A function that selects a random hole for the mole to peep from.
• Using the two functions above, create a function to make the mole emerge out of the random hole.
• A start-up function for the game.

The objective of this project is to create a Whack-a-Mole game using JavaScript. The source code is given below.

13. Rock Paper Scissors game

Anyone who has not been living under the rocks must have heard about the game Rock Paper Scissors game. Rock paper scissors is a classic two-person hand game in which each participant forms one of three shapes with their outstretched hand at the same time. Wouldn’t it be nice if we can implement it using JavaScript? The project given below is a simple DOM (Document Object Model) rock scissors paper project.

14. Real-time Weather app

This project will show you how to create a weather app using Vanilla JS, HTML, and CSS. For getting meteorological information, the instructor uses the Dark Sky API, which is a terrific opportunity for you to learn how to communicate with APIs, which is another great thing you can do with JavaScript. The only issue you might have is figuring out how to use JavaScript to interact with an API. But believe me when I say that won’t be an issue.

In this app you’re going to make: our weather app will display weather data from the API like this: an icon that represents the current weather status, the temperature value (18°C) in Celsius units, the weather description (clear sky), and finally the user’s city and country (London, GB).

The temperature value will be converted from Celsius to Fahrenheit when the user clicks on it.

JavaScript projects: Why are they so important?

The fact that JavaScript is currently used by 94.5 per cent of all websites demonstrates its relevance as a web technology. JavaScript is a client-side programming language that allows web developers to write customized client-side scripts to make web pages more dynamic and interactive. At the same time, developers can create server-side code in JavaScript using cross-platform runtime engines like Node.js. They can even integrate JavaScript, HTML5, and CSS3 to produce web pages that are compatible with all browsers, platforms, and devices. There are several other reasons why any modern web developer should be familiar with JavaScript and how to take advantage of all of its features.

JavaScript skills may lead to a variety of hard and exciting employment opportunities, such as designing mobile and desktop apps, creating dynamic websites from scratch, working as a UI/UX designer, or even working as a full-stack developer. If you know the fundamentals of JavaScript, projects are the next logical step in boosting your resume’s star rating. If you have no prior programming knowledge, you can enrol in some fundamental JavaScript classes and then return to these projects. Most JavaScript projects with the source code listed above will be understandable if you know a little HTML and CSS.

Conclusion

We have suggested some JavaScript projects categorized into beginner-level, intermediate-level, and advanced-level projects. These projects will enhance your JS skills and will add a lot of value to your portfolio. They cover practically all of the major JavaScript principles.
