Bound method performance penalty

Benchmark created on

Description

Evaluate penalty introduced by passing bound method, as opposed to ordinary function

Setup

function test_func(iterable) {
	const arr = Array.from(iterable)
	return arr.reduce((acc, cur, idx, ar) => acc + cur, 0)
}

class Tst {
	test_func(iterable) {
		const arr = Array.from(iterable)
		return arr.reduce((acc, cur, idx, ar) => acc + cur, 0)
	}
}

function caller(func, ...args) {
	return func(...args)
}

const inst = new Tst()


const arr = new Array()
for (let i = 0; i < 1000; i++) arr[i] = i ** 2
