Benchmark: Search object property value in array of object - 3

Script Preparation code:

var size = 10000
var arr = []
for (let i = 0; i < size; i++) {
    arr.push({ i })
}
var research = 6578;

function findObjectInArray(arr, prop, value) {
  	if (arr.length === 0 || !arr[0].hasOwnProperty(prop))
      return -1;
	for (let i = 0; i < size; i++) {
      	if (!arr[i].hasOwnProperty(prop))
         	continue;
		if (arr[i][prop] === value)
        	return i;
    }
    return -1;
}

Tests:

map indexof
const index = arr.map(e => e.i).indexOf(research)
custom func
const index = findObjectInArray(arr, 'i', research)
findIndex
const index = arr.findIndex(e => e.i === research)
