Javascript-Hi any insights on this please , comparing array of objects and picking the required one and checking for its value change ,this code is working but how it can be made to satsify all conditions

[#1]

I'll get array of objects "item", I have to filter out the latest object containing "Cluster deployment in progress" and then keeping
	a check on that same id conatining "Cluster deployment in progress" , when its status changes from "in-progress" to "success"
	So please help in making this piece of code to work on all conditions
	item = [
	{id:"59b6115432acd43347dd5b2b",
	notif_detail:"Cluster deployment in progress",
	notif_time:"2017-09-11T04:30:12.552Z",
	status:"in-progress"},
	{
	id:"59b6239e32acd43347dd5b57",
	notif_detail:"Cluster deployment in progress",
	notif_time:"2017-09-11T05:48:14.275Z",
	status:"in-progress"
	}
	]
	solution:-
	this.subscription = this._userService.navItem$.subscribe(item =>
	this.item1 = item)
	console.log(this.item1)
	let clustProgress = this.item1.filter(e => e.notif_detail == "Cluster
	deployment in progress")
	console.log(clustProgress);
	let mostRecClustDep = clustProgress.sort(function (a, b) {
	return new Date(b.notif_time).getTime() - new Date(a.notif_time).getTime()
	})[0];
	console.log(mostRecClustDep)
	let result = this.item1.filter(e => e.id === mostRecClustDep.id);
	console.log(result)
	let resultstat = result.map(e => e.status)
	console.log(resultstat);
	if (resultstat[0] === "in-progress") {
	//Do something
	} else {
	//Do something else
	}
