Find and remove DOM elements with JavaScript

removeel.js

/**
 * Find all the elements, that match any of the classes that are specified in the array 
 * and remove all the matching elements from the DOM
 */

// Step 1: Define the array of class names
const classesToRemove = ['elem1', 'elem2'];

// Step 2: Create the selector string
// This will create a string like ".class1,.class2,.class3"
const selector = classesToRemove.map(className => `.${className}`).join(',');

// Step 3: Select and remove the elements
document.querySelectorAll(selector).forEach(element => {
  element.parentNode.removeChild(element);
});
