Benchmark: Lodash omit vs es omit vs compiled omit vs rest and delete omit vs babel - a lot of different objects

HTML Preparation code:

Script Preparation code:

var omit1 = (originalObj = {}, keysToOmit = []) =>
    Object.fromEntries(
        Object.entries(originalObj)
        .filter(([key]) => !keysToOmit.includes(key))
    )

var omit2 = new Function('obj', 'if (!obj) return {}; const { a, d, i, ...res } = obj; return res;');

var omit3 = (originalObject = {}, keysToOmit = []) => {  
    const clonedObject = { ...originalObject };              
    for (const path of keysToOmit) {                
      delete clonedObject[path]       
    }           
    return clonedObject;
}

function omit4(obj, keys) {
  var target = {};
  for (var i in obj) {
    if (keys.indexOf(i) >= 0) continue;
    if (!Object.prototype.hasOwnProperty.call(obj, i)) continue;
    target[i] = obj[i];
  }
  return target;
}

function getRandomInt(min, max) {
  min = Math.ceil(min);
  max = Math.floor(max);
  return Math.floor(Math.random() * (max - min) + min); //The maximum is exclusive and the minimum is inclusive
}


var data = [];

for (let i = 0; i < 10000; i++) {
    const obj = {};
	const propsCount = getRandomInt(0, 10);
  
  	for (let j = 0; j < propsCount; j++) {
		
	 	const propCode = getRandomInt(97, 122);
      
  		obj[String.fromCharCode(propCode)] = propCode;
	}
  
    data.push(obj);
}

Tests:

Lodash
data.map((obj) => _.omit(obj, ['a','d','i']))
es omit
data.map((obj) => omit1(obj, ['a','d','i']))
compiled omit
data.map((obj) => omit2(obj, ['a','d','i']))
rest and delete omit
data.map((obj) => omit3(obj, ['a','d','i']))
babel
data.map((obj) => omit4(obj, ['a','d','i']))
