Benchmark: findIndex + toSpliced vs map

Script Preparation code:

var items = [{name: 'name1', value: 1},{name: 'name2', value: 1},{name: 'name3', value: 1},{name: 'name4', value: 1}];
var search = 'name4';
var result = [];

Tests:

findIndex + toSpliced
var index = items.findIndex(({name}) => name === search); if (index >= 0) { result = items.toSpliced(index, 1, {...items[index], value: 2}); }
map
result = items.map(item => item.name === search ? {...item, value: 2} : item)
