How to retrieve last element id of array in Angular 2

I am trying to get id of last element of my array.

This is how I am fetching last element of my array

let last = this.Array[this.Array.length-1]; console.log(last); 

Here is the console of last element of array-

Object {id: 48, title: "I'm used to this"} title: "I'm used to this" id: 48 __proto__: Object 

Here is the list on which I have looked already-

Just do that:

let last:any = this.Array[this.Array.length-1]; console.log(last.id); 

You can do this.Array.slice(-1)[0].id, and with slice your original array is not changed too.

DEMO :

var array = [{ id: 43, title: "I'm used to this" },{ id: 44, title: "I'm used to this" },{ id: 45, title: "I'm used to this" },{ id: 46, title: "I'm used to this" },{ id: 47, title: "I'm used to this" },{ id: 48, title: "I'm used to this" }] console.log('last id : ' + this.array.slice(-1)[0].id)

Update:

As your Array item is type of Object, So first convert it to some real class\interface type, Something like:

export interface arrayItem{ id?: number; title?: string; } 

then define your array type, like :

your Array like

this.Array : Array<arrayItem> = [ { id: 48, title: "I'm used to this" }, //your other array items ]
