How to usea For Loop in Javascript
We can use a loop to iterate through the array of images and display each image using the <img> tag.
Example: In this example, we have an array of image URLs, and we use a for loop to iterate through the array and create an <img> tag for each image. We set the src attribute of each <img> tag to the corresponding image URL and append it to the container element.
<!DOCTYPE html>
<html>
<head>
<title>Display Images from Array</title>
</head>
<body>
<h1 style="color: green;">

<h1>Display Images from Array using a Loop</h1>
<div id="image-container"></div>
<script>
const images = [
'https://media.w3wiki.org/wp-content/uploads/20230306120634/unnamed.jpg',
'https://media.w3wiki.org/wp-content/uploads/20230306120634/unnamed.jpg',
'https://media.w3wiki.org/wp-content/uploads/20230306120634/unnamed.jpg'
];
const container = document.getElementById('image-container');
for (let i = 0; i < images.length; i++) {
const img = document.createElement('img');
img.src = images[i];
container.appendChild(img);
}
</script>
</body>
</html>

How to display images from an array in JavaScript ?
Displaying images from an array in JavaScript involves storing image URLs within the array and dynamically generating HTML elements, such as <img>, using JavaScript. By iterating over the array, each image URL is used to create <img> elements, which are then appended to the document for display.
Below are the approaches that could be used to display images from an array in JavaScript
Table of Content
- Using a For Loop
- Using Array.map() Method
- Using a forEach() method
Syntax:
<img src="image-url" alt="alternative-text">
Here, the src attribute specifies the URL of the image, and the alt attribute provides alternative text for the image if it cannot be displayed.
