How to remove element from array

• we can change the length of the array

const arr = [1,2,3,4]
arr.length = 2 // [1,2]

• Array.pop() - will remove the last element and return it
• Array.shift() - will remove the first element and return it
• Array.splice()

const arr = [1,2,3,4]
arr.splice(1,1) // [1,3,4]

There are some other methods, this is only the basics.
