small Set versus Array iteration

Benchmark created on

Setup

const objectsArray = Array.from({length: 25}).map((_, i) => ({ name: `Hello${i}`, i }))

const objectsArrayWithRepeats = objectsArray.flatMap((object, i) => {
	if (i % 3 === 0) {
		return [object]
	}
	else if (i % 3 === 1) {
		return [object, object]
	}
	return [object, object, object]
})

const objectsSet = new Set(objectsArray)
