JavaScript for Beginners #32 Basic Array Methods & Properties | push() | unshift() | pop() | shift()
Here, we will learn about a few basic array methods: push to add an item to the end of an array, unshift to add an item to the beginning, pop to remove an item from the end, and lastly shift to remove an item from the beginning. Additionally, we will learn about the length property, which gives us the length of an array. Since arrays are zero-indexed, we can use array.length - 1 to always find the position of the last item or array.length to add an item to the end of an array.
