Write sorting for date and name in javascript?

Question

How to write sorting for date and name in js?

i have one table. there are 2 column like name and created date

name: ["A", "A9", "A10", "A11", "A3"]

createdDate: ["Apr 2, 2019 3:07 PM", "Apr 10, 2019 9:25 AM", "Apr 30, 2019 6:08 PM", "Apr 10, 2019 8:25 AM", "Apr 2, 2019 8:07 PM"]

and output should like this :

name: ["A", "A3", "A9", "A10", "A11"]

createdDate: ["Apr 2, 2019 3:07 PM", "Apr 2, 2019 8:07 PM","Apr 10, 2019 8:25 AM", "Apr 10, 2019 9:25 AM", "Apr 30, 2019 6:08 PM"]

 

 

I already try using sort method.

.sort(a,b){

var firstEl = (a === undefined) ? a :a.toUpperCase();

var secondEl = (b === undefined) ? b: b.toUpperCase();

if(firstEl === undefined || firstEl === "") {return (1)}

if(secondEl === undefined || secondEl === "") {return (-1)}

if(firstEl === secondEl) {return 0;}

return firstEl < secondEl ? (-1) : (1 );

} 

but its not workign for alhanumeric value
