Top JavaScript Projects to Develop

This section will explain various JavaScript projects with their source code, which will help you understand everything easily.

1. Hex Color Application

Hex color is a six-digit code of the color that you can use to create color. So the application efficiently changes the background color when you press a single button.

It also displays the hexadecimal value for more clarity. The objective of this project is to generate a random hex color and, after doing so, set it as the background color. Here is the exemplary source code:

<!DOCTYPE html>
<html>
<head>
  <title>Choose A Color</title>
  <style>
    body {
      margin: 2;
      padding: 2;
      display: grid;
      place-items: center;
      height: 50vh;
      font-size: 20px;
    }
    .main {
      height: 200px;
      width: 550px;
      background: #FFC90e;
      border-radius: 5px;
      display: grid;
      place-items: center;
      color: #00000;
      font-family: Impact;
      border-radius: 25px;
    }
    #colorPicker {
      background-color: none;
      outline: none;
      border: none;
      height: 80px;
      width: 80px;
      cursor: pointer;
    } 
    #box {
      outline: none;
      border: 4px solid #000;
      border-radius: 30px;
      height: 25px;
      width: 90px;
      padding: 0 10px;
    }
  </style>
</head>
<body>
  <h1>Choose A Color</h1>
  <div class="main">
    Color Picker: <input type="color"
      id="colorPicker" value="#35cdde">
    Enter Hex Code: <input type="text" id="box">
  </div>
  <script>
    function myColor() {
      var color = document.getElementById('colorPicker').value;
      document.body.style.backgroundColor = color;
      document.getElementById('box').value = color;
    }
    document.getElementById('colorPicker')
      .addEventListener('input', myColor);
  </script>
</body>
</html>

2. Random Quote Generator

In this JavaScript project, you must build an app that displays famous random quotes every time the user clicks a button. To build this project, you need knowledge of basic JavaScript concepts like object literals, loops, and variables.

By working on a JavaScript project like the Random Quote Generator, you’ll be able to practice your JavaScript skills in an effective and fun way. Plus, it can be a small portfolio addition to help showcase your JavaScript knowledge to recruiters.

You can use the following source code as an example to create a random quote generator:

HTML Code

<!DOCTYPE html>
<html>
<head>
  <link rel="stylesheet" href="style.css"/>
</head>
<body id="body">
  <div>
  <div class="block text-center">
  <div class = "quote-box block__main block__front">
  <span class = "quote">
    <i class="fas fa-2x fa-quote-left"></i>
    <span class = "text">
    </span>
  </span>
  <div class = "author">
   </div>
  <a class = "new-quote btn btn-default"
    onclick="newQuote()">New Quote</a>
  </div>
  <div class = "quote-box block__main block__back">
  <span class = "quote">
       <i class="fas fa-2x fa-quote-left"></i>
    <span class = "text">
    </span>
  </span>
  <div class = "author">
  </div>
    <a class = "new-quote btn btn-default "
      onclick="newQuote()">New Quote</a>
  </div>
</div>
</div>
<script src="script.js"></script>
</body>
</html>

    this.data = data;
    displayQuote()
});
function newQuote(){
  blockBack.classList.toggle('rotateB');
  blockFront.classList.toggle('rotateF');
  displayQuote();
}

3. JavaScript Calculator

The idea of this project is to create a classic calculator. You can create a nice-looking, functional calculator using CSS for beautification and HTML for creating the structure of the calculator.

The performance and function of the buttons on the calculators require the use of JavaScript. In the calculator, you can add basic functions like multiplication, division, addition, and so on, as well as the functions of a scientific calculator.

<!DOCTYPE html>
<html lang = "en">
<head>
<style>
h1 {
  text-align: center;
  padding: 30px;
  background-color: #ffc90e;
  color: #00000;
  }
#clear{
width: 360px;
border: 1px solid black;
  padding: 12px;
  background-color:#ffc90e;
}
.formstyle

  <br>
</form>
</div>
</body>
</html>

4. Animated Counter

A simple animated counter to display a counter starting from zero to infinite. Many websites use this type of counter to make their web pages attractive and amazing.

Hence, it is good to create animated counters using various JS concepts. For example:

<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1.0"/>
<style>
canvas {
    border:2px solid #000000;
    background-color: #ffffff;
}
</style>
</head>
<body onload="startGame()">
<script>
var myGamePiece;
var myObstacles = [];
var myScore;
function startGame() {
    myGamePiece = new component(25, 25, "yellow", 10, 100);
    myGamePiece.gravity = 0.05;
    myScore = new component("20px", "Impact", "red", 200, 50, "text");
    myGameArea.start();
}
var myGameArea = {
    canvas : document.createElement("canvas"),
    start : function() {
        this.canvas.width = 600;
        this.canvas.height = 400;
        this.context = this.canvas.getContext("2d");
        document.body.insertBefore(this.canvas, document.body.childNodes[0]);
        this.frameNo = 0;
        this.interval = setInterval(updateGameArea, 20);
        },
    clear : function() {
        this.context.clearRect(0, 0, this.canvas.width, this.canvas.height);
    }
}
function component(width, height, color, x, y, type) {
    this.type = type;
    this.score = 0;
    this.width = width;
    this.height = height;
    this.speedX = 0;
    this.speedY = 0;    
    this.x = x;
    this.y = y;
    this.gravity = 0;
    this.gravitySpeed = 0;
    this.update = function() {
        ctx = myGameArea.context;
        if (this.type == "text") {
            ctx.font = this.width + " " + this.height;
            ctx.fillStyle = color;
            ctx.fillText(this.text, this.x, this.y);
        } else {
            ctx.fillStyle = color;
            ctx.fillRect(this.x, this.y, this.width, this.height);
        }
    }
    this.newPos = function() {
        this.gravitySpeed += this.gravity;
        this.x += this.speedX;
        this.y += this.speedY + this.gravitySpeed;
        this.hitBottom();
    }
    this.hitBottom = function() {
        var rockbottom = myGameArea.canvas.height - this.height;
        if (this.y > rockbottom) {
            this.y = rockbottom;
            this.gravitySpeed = 0;
        }
    }
    this.crashWith = function(otherobj) {
        var myleft = this.x;
        var myright = this.x + (this.width);
        var mytop = this.y;
        var mybottom = this.y + (this.height);
        var otherleft = otherobj.x;
        var otherright = otherobj.x + (otherobj.width);
        var othertop = otherobj.y;
        var otherbottom = otherobj.y + (otherobj.height);
        var crash = true;
        if ((mybottom < othertop) || (mytop > otherbottom) || (myright < otherleft) || (myleft > otherright)) {
            crash = false;
        }
        return crash;
    }
}
function updateGameArea() {
    var x, height, gap, minHeight, maxHeight, minGap, maxGap;
    for (i = 0; i < myObstacles.length; i += 1) {
        if (myGamePiece.crashWith(myObstacles[i])) {
            return;
        }
    }
    myGameArea.clear();
    myGameArea.frameNo += 1;
    if (myGameArea.frameNo == 1 || everyinterval(150)) {
        x = myGameArea.canvas.width;
        minHeight = 20;
        maxHeight = 200;
        height = Math.floor(Math.random()*(maxHeight-minHeight+1)+minHeight);
        minGap = 50;
        maxGap = 200;
        gap = Math.floor(Math.random()*(maxGap-minGap+1)+minGap);
        myObstacles.push(new component(20, height, "black", x, 0));
        myObstacles.push(new component(20, x - height - gap, "black", x, height + gap));
    }
    for (i = 0; i < myObstacles.length; i += 1) {
        myObstacles[i].x += -1;
        myObstacles[i].update();
    }
    myScore.text="SCORE: " + myGameArea.frameNo;
    myScore.update();
    myGamePiece.newPos();
    myGamePiece.update();
}
function everyinterval(n) {
    if ((myGameArea.frameNo / n) % 1 == 0) {return true;}
    return false;
}
function accelerate(n) {
    myGamePiece.gravity = n;
}
</script>
<br>
<button onmousedown="accelerate(-0.2)" onmouseup="accelerate(0.05)">UP</button>
<p>Press the UP button</p>
</body>
</html>

5. To-Do List

A to-do list is handy when storing important information and holding things on track. You can also create an interactive to-do list using JavaScript codes. It requires simple codes, but it definitely impacts your technical skills positively. Here is the example source code you can try to create a to-do list using JavaScript codes:

<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">
<style>
body {
  margin: 0;
  min-width: 145px;
}
