How to usea forEach() method in Javascript

We can iterate over the whole array of elements using the forEach() method and can display image using <img> tag.

Example: In this example, we have an array of image URLs, and we use a forEach() 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.

HTML

<!DOCTYPE html>
<html>
<head>
    <title>Display Images from Array</title>
</head>

<body>
    <h1 style="color: green;">
        w3wiki
    </h1>

    <h1>
          Display Images from Array using 
          Array.forEach()
      </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');
        images.forEach(image => {
            const img = document.createElement('img');
            img.src = image;
            container.appendChild(img);
        })
    </script>
</body>
</html>

Using forEach()

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.
