Can I use querySelectorAll to count elements with a specific class?

Answers:

• Yes, you can use querySelectorAll to count elements with a specific class in JavaScript. The querySelectorAll method returns a NodeList of all elements that match a specified CSS selector. You can then measure the length of this NodeList to get the count of elements with that class.

  Here’s an example:

  // Replace 'your-class-name' with the actual class name you want to count
  const elements = document.querySelectorAll('.your-class-name');
  const count = elements.length;
  
  console.log(`Count of elements with the class 'your-class-name': ${count}`);
  

  In this example, '.your-class-name' is the CSS selector used to find all elements with the specified class. The length property of the NodeList (elements) will give you the count of matched elements.
