Array vs Array-Like Objects in JavaScript – Learn the Difference

The main similarities between a regular array and an array-like object are as follows:

  • They both have the length property.
  • The two object's properties start from the zeroth (0) index.

Here are the main differences between the two objects:

  • An array-like object has only a few—not all—of the features of a regular JavaScript array.
  • An array-like object does not have built-in methods like map(), pop(), and forEach(). However, a regular array has those methods.
tip

You can use the spread operator or the Array.from() method to convert an array-like object to a regular array.
