Benchmark: Native findIndex vs Custom findIndex

Script Preparation code:

var arr = new Array(100).fill(null).map((val, idx) => {
return {
id: idx + 1,
text: idx
};
});

Tests:

Native findIndex
arr.findIndex((zoom) => { return zoom.id === 30; });
Custom findIndex
let length = arr.length; for(let idx = 0 ; idx < length ; idx++) { let zoom = arr[idx]; if(zoom.id === 30) {return idx;} }
