Benchmark: Lodash reduce filter vs Native reduce filter vs Lodash filter vs Native filter

HTML Preparation code:

<script src='https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.5/lodash.min.js'></script>

Script Preparation code:

var testCopy = null;
var testArray = [{
  id: 1,
  description: 'Random description.',
  testDate: new Date(),
  testBoolean: true,
  testObject: {
    testString: 'test string',
    testNumber: 12345
  },
  testArray: [{
    myName: 'test name',
    myNumber: 123245
  }]
},{
  id: 2,
  description: 'Random description.',
  testNumber: 123456789,
  testBoolean: true,
  testObject: {
    testString: 'test string',
    testNumber: 12345
  },
  testArray: [{
    myName: 'test name',
    myNumber: 123245
  }]
}];

Tests:

Reduce filter
testCopy = testArray.reduce((accumulator, currentValue) => { if(currentValue.id != 2) { currentValue.description = 'test'; accumulator.push(currentValue); return accumulator; } return accumulator; },[])
Lodash reduce filter
testCopy = _.reduce(testArray,(accumulator, currentValue) => { if(currentValue.id != 2) { currentValue.description = 'test'; accumulator.push(currentValue); return accumulator; } return accumulator; },[]);
Native filter
testCopy = testArray.filter(o => { if(o.id != 2) { o.description = 'test'; return o; } });
Lodash filter
testCopy = _.filter(testArray, function(o) { if(o.id != 2) { o.description = 'test'; return o; } });
Reduce modify
testCopy = testArray.reduce((accumulator, currentValue) => { if(currentValue.id == 2) { currentValue.description = 'test'; accumulator.push(currentValue); return accumulator; } return accumulator; },[])
Map modify
testCopy = testArray.map((item)=>{ if(item.id == 2){ item.description = 'test'; } return item; });
