Deep copy an array in Angular 2 + TypeScript

Simple:

let objCopy  = JSON.parse(JSON.stringify(obj));

This Also Works (Only for Arrays)

let objCopy2 = obj.slice()

Check this:

  let cloned = source.map(x => Object.assign({}, x));

This is working for me:

this.listCopy = Object.assign([], this.list);
