Is querySelectorAll() supported in all browsers?

Answers:

• The querySelectorAll() method is widely supported across modern browsers. It was introduced in the DOM Level 3 specification and is supported in:

  • Chrome (from version 1)
  • Firefox (from version 3.5)
  • Safari (from version 3.1)
  • Opera (from version 9.5)
  • Internet Explorer (from version 8)

  Given that these browsers are still commonly used, querySelectorAll() can be considered safe to use in most web development projects.

  However, if you need to support very old browsers (such as Internet Explorer 7 and earlier), querySelectorAll() will not work. For environments where support for such old browsers is unnecessary, you can confidently use this method to select elements in the DOM.

  Always consider checking for feature support or using polyfills in scenarios where older browser compatibility is essential.
