Make a code that plays a random audio from an array
javascript Copy code
const audioArray = ["audio1.mp3", "audio2.mp3", "audio3.mp3", "audio4.mp3"];
function playRandomAudio() {
const audioIndex = Math.floor(Math.random() * audioArray.length);
const audio = new Audio(audioArray[audioIndex]);
audio.play();
}
In this code, we first create an array named audioArray which contains the names of audio files we want to randomize.
After that, we create a function named playRandomAudio() that picks a random index number from audioArray using Math.random().
We then create a new Audio object with the random audio file name we generate in the previous step, and finally use play() method to play the audio file.
👩💻 Make. A game
Here's an example of a simple game created in JavaScript - "Guess the Number".
javascript Copy code
let randomNumber = Math.floor(Math.random() * 100) + 1;
let guessCount = 0;
let guess;
function makeGuess() {
guess = Number(document.getElementById("guess").value);
guessCount++;
if (guess === randomNumber) {
alert(`Congratulations, you guessed the number in ${guessCount} tries!`);
} else if (guess < randomNumber) {
alert("The number you guessed is too low. Try a higher number");
} else if (guess > randomNumber) {
alert("The number you guessed is too high. Try a lower number");
}
}
In this game, the computer generates a random number between 1 and 100, and then the player enters their guess. If the player's guess matches the generated number, they win the game. If the guess is too high or too low, the game will provide a hint to the player so that they can guess again.
The HTML code for the game:
html Copy code
<body>
<h1>Guess the Number</h1>
<p>Can you guess the number the computer is thinking of?</p>
<label for="guess">Enter your guess:</label>
<input type="number" id="guess">
<button onclick="makeGuess()">Guess</button>
</body>
In this HTML code, we create an input field where the player can enter their guess. We then create a button labeled "Guess" which, when clicked, will call the makeGuess() function which will evaluate the user's guess.
Note: This is just a simple example, but it's a good starting point to build more complex games in JavaScript.
👩💻 Make A Pattern Game
Here's an example of a simple game created in JavaScript - "Pattern Game".
javascript Copy code
const pattern = ["red", "green", "blue", "yellow"]; // Pattern to match
let currentLevel = 0; // Current level of the game
let userPattern = []; // Array to store the user's pattern
let isPlaying = false; // Flag to check whether the game is currently being played
// When the user clicks the start button
function startGame() {
if (!isPlaying) {
isPlaying = true;
currentLevel = 0;
userPattern = [];
nextLevel();
}
}
// Generate the next items of the pattern and add them to the page
function nextLevel() {
currentLevel++;
userPattern = [];
const patternToMatch = [...pattern].splice(0, currentLevel);
displayPattern(patternToMatch);
}
// Display each item of the pattern to the user
function displayPattern(pattern) {
let i = 0;
const intervalId = setInterval(function() {
if(i == pattern.length) {
clearInterval(intervalId);
return;
}
highlight(pattern[i]);
i++;
}, 1000);
}
// Add highlight to the item and remove after one second
function highlight(item) {
const el = document.getElementById(item);
el.classList.add('highlight');
setTimeout(() => {
el.classList.remove('highlight');
}, 500);
}
// Handle user's click on the item
function handleClick(item) {
if(isPlaying) {
userPattern.push(item);
if (userPattern.length === currentLevel) {
checkPattern();
}
}
}
// Check whether the user's pattern matches the current level's pattern.
function checkPattern() {
let success = true;
for (let i = 0; i < currentLevel; i++) {
if (userPattern[i] !== pattern[i]) {
success = false;
break;
}
}
if (success) {
if (userPattern.length === pattern.length) {
alert('Congratulations! You won the game!');
isPlaying = false;
} else {
setTimeout(() => {
nextLevel();
}, 1000);
}
} else {
alert('Sorry! Wrong pattern. You lost the game!');
isPlaying = false;
}
}
In this game, the computer generates a pattern of colors (indicated by the pattern variable). The player has to match each item of the pattern by clicking on the corresponding color button. If the user clicks the right sequence of items in the pattern, the computer generates the next level by adding one more item to the pattern. If the user clicks an incorrect item, the game is over.
The HTML code for the game:
html Copy code
<body>
<h1>Pattern Game</h1>
<p>Click the colored boxes in the order they light up.</p>
<div class="buttons">
<button class="button" id="red" onclick="handleClick('red')"></button>
<button class="button" id="green" onclick="handleClick('green')"></button>
<button class="button" id="blue" onclick="handleClick('blue')"></button>
<button class="button" id="yellow" onclick="handleClick('yellow')"></button>
</div>
<button class="start-button" onclick="startGame()">Start game</button>
</body>
In this HTML code, we create four buttons, each corresponding to a color of the pattern, where the player can click to make their guess. We also created a "Start game" button that will initialize the game when clicked. We also added a CSS class named 'highlight' that will be used to highlight the button when the pattern is displayed.
Please, write a small website (one page) dedicated a famous actress Angelina Jolie including 1 video, 3 pictures, 2 audio recording and a grid.
Below is an example of a webpage dedicated to Angelina Jolie using HTML, CSS and Javascript:
html Copy code
<!DOCTYPE html>
<html>
<head>
<title>Angelina Jolie</title>
</head>
<style>
body {
text-align: center;
font-family: Helvetica;
}

how play local audio in react js app component
To play a local audio file in a ReactJS app component, you can use the React Audio Player package. Here is an example of how to use it:
jsx Copy code
import React from 'react';
import AudioPlayer from 'react-audio-player';
export default class App extends React.Component {
render() {
return (
<div>
<AudioPlayer
src="my-audio-file.mp3"
onPlay={(e) => console.log(e)}
/>
</div>
);
}
}
How to do an 3D audio-reactive script in p5.js?
You can use the p5.sound library in p5.js to access sound information, like amplitude or frequency. You can combine this with the p5.js library p5.js-extras to create an audio-reactive 3D script.
The sketch below is a basic example of an 3D audio-reactive visualizer using p5.js. Notice that we use the p5.sound library within the setup() and draw() functions to access sound data.
javascript Copy code
// create a canvas
var cnv = createCanvas(512, 512);
// create an audio element using p5.sound
var mySound;
function preload() {
mySound = loadSound('./music.mp3');
}
function setup(){
mySound.play(); // play the audio on load
// access the amplitude of the sound
amplitude = new p5.Amplitude();
}
function draw(){
background(51);
// get the audio frequency spectrum
spectrum = amplitude.getLevel();
// use the spectrum to change the size of the sphere
var size = map(spectrum, 0, 1, 0, 500);
// draw a 3D sphere
push();
noStroke();
fill(255);
translate(250,250,-50);
sphere(size);
pop();
}
How to add music to the background of a page
To add music to a web page in HTML, you can use the
html Copy code
<audio src="music.mp3" controls="true" loop="true" preload="auto" autoplay="true"></audio>
This will embed an audio file called music.mp3 and set the following properties:
controls="true" - Displays the audio controllerloop="true" - Continuously loops the audio filepreload="auto" - Preloads the audio file on page loadautoplay="true" - Begins playing the audio as soon as it is ready.Note that autoplay tends to be blocked in most browsers. For a more comprehensive example, see this page: https://www.w3schools.com/html/html5_audio.asp

Athena was the Greek goddess of wisdom, among other elements. She received her name from the city of Athens, which she is known for protecting.
Much like the goddess Athena, SheCodes Athena is also incredibly wise and can solve complicated coding puzzles in a matter of seconds! 😍
Not likely. AI can automate tasks and make developers' jobs more efficient but it can't fully replace the human ability to deal with complex software. And AI will still require human developers to supervise and improve it further.
So developers may see their tasks change but they won't be replaced by AI. 👩💻🤝💻
