You're debugging a JavaScript application and notice unexpected behavior in the manipulation of an array. The items are not being removed correctly using a method, and it turns out the array is not being modified at all. Which array method might be mistakenly being used?

  • pop()
  • push()
  • splice()
  • concat()
The concat() method is often mistakenly used for removing elements from an array because it doesn't modify the original array but returns a new array instead. The correct method for removing elements from an array is splice() or other methods like pop() or shift().
