Question

Which array method in JavaScript is used to insert an element at the beginning of an array ?

• A. push()
• B. unshift()
• C. concat()
• D. pop()

Hint:

To remember this: push/pop work on the end of the array, whereas unshift/shift work on the beginning of the array. The longer word in each pair adds elements (push, unshift), while the shorter word removes elements (pop, shift).
