Test name	Executions per second
Math.min with spread and map	39552.8 Ops/sec
For loop with bitwise min	4094.6 Ops/sec

Script Preparation code:

var arrays = Array(1000).fill(() => Array(Math.random() * 1000).fill(0));

function bitwiseMin(x, y) {
  return y ^ ((x ^ y) & -(x < y));
}

Tests:

Math.min with spread and map
var smallest = Math.min(...arrays.map(arr => arr.length));
For loop with bitwise min
var smallest = arrays[0].length; for (var i = 1; i < arrays.length; i++) { smallest = bitwiseMin(smallest, arrays[i].length) }
