For example, we have a 2D arrays;
const arys = [ [‘abw‘, 3], [‘bcd‘, 2], [‘dcw‘, 2] ];
We want to sort by the number first, if the number are the same, then we want to sort by name DESC:
So the result should be:
[ [ ‘abw‘, 3 ], [ ‘dcw‘, 2 ], [ ‘bcd‘, 2 ] ]
const result = arys.sort((a, b) => { if (b[1] > a[1]) { return true } else if (b[1] < a[1]) { return false; } else { return b[0].toLowerCase().localeCompare(a[0].toLowerCase()) } });
