Test name Executions per second
Math.max 16383.5 Ops/sec
Reduce 5669.8 Ops/sec
for element of array 43165.4 Ops/sec
Script Preparation code:
​x
 
var values = new Array(5000);
​
for (let i = 0; i < values.length; ++i) {
    values[i] = i % 20;
}
Tests:

  • Math.max

     
    return Math.max(...values);

  • Reduce

     
    return values.reduce((prev, curr) => {
      if (curr > prev) return curr;
      return prev;
    }, 0);

  • for element of array

     
    let biggest = values[0];
    for (let value of values) {
      if (value > biggest) biggest = value;
    };
    return biggest;
