Can querySelectorAll() select elements by class name?

Answers:

• Yes, querySelectorAll() can be used to select elements by class name. You can do this by using the class selector syntax in your query string. For example, if you want to select all elements with the class name example, you can use the following JavaScript code:

  const elements = document.querySelectorAll('.example');
  

  In this example, the . before example indicates that you are selecting elements by their class name. The querySelectorAll() method returns a NodeList of all matching elements, which you can then iterate over or manipulate as needed. Keep in mind that if no elements match the specified class name, an empty NodeList will be returned.
