How to find the min/max date javascript

Question

Im try to get the min and max date from an array in Javascript but I'm getting this error NaN

here the little code:

var dates = [];


var fecha1 =  "2020-05-05 15:00:00";
var fecha2 =  "2020-05-05 16:00:00";
var fecha3 =  "2020-05-06 13:00:00";
                dates.push(fecha1);
                dates.push(fecha2);
 dates.push(fecha3);

console.log(dates);

  var maximumDate=Math.max.apply(null, dates);
  var minimumDate=new Date(Math.min.apply(null, dates));
console.log(maximumDate);

I hope i explained well

A date is not a number, you should convert it to an int value like epoch or unix timestamp. — Wimanicesir, May 07 '20 at 15:54
As the name suggests, `Math.max` gets the *mathematical* max. Date strings are not mathematical. — SOFe, May 07 '20 at 15:54

Solution is of coarse here on SO: https://stackoverflow.com/a/7143443/7158959 You are already using first suggestion from that link, you should just try second one. Flag in it as duplicate.

var dates = [];


var fecha1 =  "2020-05-05 15:00:00";
var fecha2 =  "2020-05-05 16:00:00";
var fecha3 =  "2020-05-06 13:00:00";
                dates.push(fecha1);
                dates.push(fecha2);
 dates.push(fecha3);

console.log(dates);

var min = dates.reduce(function (a, b) { return a < b ? a : b; }); 
var max = dates.reduce(function (a, b) { return a > b ? a : b; });
console.log(min);
console.log(max);
