Test name	Executions per second
Array.prototype.find	814.2 Ops/sec
Array.prototype.findIndex	820.4 Ops/sec
Array.prototype.some	813.1 Ops/sec

Script Preparation code:

var arr = [];
var i = 0;

while (i <= 1E5) arr[i] = i++;

Tests:

Array.prototype.find
const item = arr.find(item => item == 1E5);
Array.prototype.findIndex
const index = arr.findIndex(item => item == 1E5);
Array.prototype.some
const index = arr.some(item => item == 1E5);

Run results for: find vs findIndex vs some (Array prototype methods)

Measuring which is faster

Array.prototype.find

Array.prototype.findIndex

Array.prototype.some
