Deep copy an array in Angular 2 + TypeScript

Question

I have an array of objects that is an input. Lets call it content.

When trying to deep copy it, it still has a reference to the previous array.

Answer 1

you can use use JQuery for deep copying :

var arr =[['abc'],['xyz']];
var newArr = $.extend(true, [], arr);
newArr.shift().shift();

console.log(arr); //arr still has [['abc'],['xyz']]
