  arr.push({a: Math.random() });
}

var arr = [];for (var i = 0; i < 99999; i++) {  arr.push({a: Math.random() });}

Tests:

const lastOrder = arr.sort((a, b) => b.a - a.a);

 
const lastOrder = arr.sort((a, b) => b.a - a.a);

const b = arr.map(a => a.a);
const v = Math.max(...b);

 
const b = arr.map(a => a.a);const v = Math.max(...b);
