Hello everyone!
I have a question about the array methods.
When we use unshift() do we have to use shift() first?

No we don’t. shift() deletes from first index in an array, unshift() adds to the first position. Say i have this array called myArray = [0,1,2,3], and i decide to kick 0 out of my array, i would just type myArray.shift(). This leaves me with myArray = [1,2,3].
six seconds later or almost immediately, i could decide to throw zero back(since it is a number either-ways) or any other number, i would now say myArray.unshift(0); which brings my array back to myArray = [0,1,2,3].
Now, you see, i could use both methods if the need be, but i dont have to
