Script Preparation code:

var data = [];
for (var i = 0; i < 100000; ++i) data.push(Math.random());

Tests:

Math.Min
Math.min(...data);
Math.Max
Math.max(...data);
Reduce for min
data.reduce((min, cur) => min > cur ? cur : min, data[0]);
Reduce for max
data.reduce((max, cur) => max < cur ? cur : max, data[0]);
For for min
var min = data[0]; for (var i = 1; i < data.length; ++i) { var c = i; if (min > c) min = c; }
For for max
var max = data[0]; for (var i = 1; i < data.length; ++i) { var c = i; if (max < c) max = c; }
For of for min
var min = data[0]; for (var c in data) { if (min > c) min = c; }
For of for max
var max = data[0]; for (var c in data) { if (max < c) max = c; }
