Get min and max value from array of objects in JavaScript
This is very similar to finding min/max value from an array of primitive data.
let persons = [{Name:"John",Age:12},{Name:"Joe",Age:5}];
let min = Math.min.apply(null, persons.map(function(a){return a.Age;}))
,max = Math.max.apply(null, persons.map(function(a){return a.Age;}))
//min - 5 , max - 12
