Question

I have an array like this

I want the Last array element to be placed in first position , the sorted array should like this

var column = ["name","generic complaint", "epidemic complaint", "epidemic1 complaint", "epidemic2 complaint", "bal vivah"] 

need the solution in typescript

Answer 1

It's quite easy:

let last = column.pop();
column.unshift(last);

Pop is used to remove the last variable but you can assign it. Unshift will add a new item at the start of an array.
