How to get age from date string using angular 2

Question

I have to check the age validation, so I have tried the following method for getting age:

let newDate = new Date(this.userDob);
var timeDiff = Math.abs(Date.now() - newDate);
let age = Math.floor((timeDiff / (1000 * 3600 * 24)) / 365);

here this.userDob is a string. How can I use this string to get age using javascript?

I don't think this question relates to angular, just to javascript data manipulation — Blundering Philosopher

@RahulBridge - in the code you posted, you're not using the angular framework. new Date(...) and Math.abs(...) and Math.floor(...) are pure javascript functions that don't require the angular library. — Blundering Philosopher

I have done it using like this,

var dob = //Here Im getting dob
var today = new Date();
var birthDate = new Date(dob);
var age = today.getFullYear() - birthDate.getFullYear();
var m = today.getMonth() - birthDate.getMonth();
if (m < 0 || (m === 0 && today.getDate() < birthDate.getDate())) {
    age--;
}

Now I'm able to check the age
