Benchmark: Object array search by property

Script Preparation code:

a = [];
for(var i=0;i<10000;i++){
  a.push({index:i,data:"blabla",randomField:"foobarfoobarfoobarfoobar",date:Date.now()});
}
var indexToFind = 5780;

Tests:

for loop
ind = -1; for(var i =0;i<a.length;i++){ if(a[i].index == indexToFind){ ind = i; } } a[ind].data;
javascript array.find
a.find(x => x.index == indexToFind).data;
javascript array.find with function
a.find(function(cv,i){ return cv.index == indexToFind;}).data;
javascript array.find with function and index
a.find(function(cv,i){ if(cv.index == indexToFind){ ind = i; return true; }else return false; }).data;
