Benchmark: Max and Min values

Script Preparation code:

var data = []
   
for (var x = 1; x <= 100000; x++) {
  data.push({ x: x, y: Math.floor(Math.random() * (1000000)) })
}

Tests:

Reduce
function getMinY() { return data.reduce((min, p) => p.y < min ? p.y : min, data[0].y); } function getMaxY() { return data.reduce((max, p) => p.y > max ? p.y : max, data[0].y); } const min = getMinY(); const max = getMaxY();
For
function getMinY(){ var minY = data[0].y; for (var i = 1; i < data.length; i++) { if (data[i].y < minY) { minY = data[i].y; } } return minY; } function getMaxY(){ var maxY = data[0].y; for (var i = 1; i < data.length; i++) { if (data[i].y > maxY) { maxY = data[i].y; } } return maxY; } var min = getMinY(); var max = getMaxY();
