So when are we allowed to perform methods like shift and pop it means that arrays are mutable right? I can see that we are able to change the same array unlike strings

let arr = [5,8,10,7,9,11] //replace with [7,9,11] to [17,19,111] let a = arr.splice(3,3,17,19,111) console.log(arr) //adding 100 on the last index of array let b = arr.unshift(100) console.log(arr) //insert 200 in last but one position let c = arr.splice(6,0,200) console.log(arr) //insert 1000 at the end let d = arr.push(1000) console.log(arr) //insert 0 on the middle of the index let insert = arr.splice(arr.length -5,0,0) console.log(arr)
