Benchmark: Min/max for array

Script Preparation code:

var data = [ ...Array(100).keys() ].map(() => {
  let value = Math.floor(Math.random() * 10000);
  if(value > 9000) return {value: null};
  return {value};
});

Tests:

Math.min/max with spread
let testData = data.map(d => d['value']).filter(d => d != null); let hasValidValues = testData.length > 0; var min = Math.min(...testData); var max = Math.max(...testData);
forEach
let min = Number.MAX_VALUE; let max = Number.MIN_VALUE; let hasValidValues = data.some(d => d['value']); data.forEach(obj => { const value = obj['value']; if (value == null) return; if (value < min) min = value; if (value > max) max = value; });
Reducer
let hasValidValues = data.some(d => d['value'] != null); const res = data.reduce((acc, d) => { const value = d['value']; if(value != null){ if (value < acc.mmin) acc.min = value; if (value > acc.max) acc.max = value; } return acc; }, {min: Number.MAX_VALUE, max: Number.MIN_VALUE});
forEach with hasValidValues in loop
let min = Number.MAX_VALUE; let max = Number.MIN_VALUE; let hasValidValues = false; data.forEach(obj => { if ('value' in obj) { const value = obj['value']; if (value === null) return; hasValidValues = true; if (value < min) min = value; if (value > max) max = value; } });
apply
let testData = data.map(d => d['value']).filter(d => d != null); let hasValidValues = testData.length > 0; var min = Math.min.apply(null, testData); var max = Math.max.apply(null, testData);
