Test name	Executions per second
Recursion	26245144.0 Ops/sec
While	36789148.0 Ops/sec

Script Preparation code:

const response = Array(1000).fill(null).map((item, index) => `foo ${index}`)

const getData = async () => {
	await new Promise(resolve => setTimeout(() => resolve(), 1000))
    return response
}

Tests:

Recursion
let items = [] const getItems = async (nextPage = 0) => { const _res = await getData() items.push(_res) if (nextPage < 5) { await getItems(nextPage + 1) } }
While
let items = [] const getItems = async (nextPage = 0) => { const _res = await getData() items.push(_res) let _nextPage = nextPage while (_nextPage < 5) { const _res = await getData() items.push(_res) _nextPage += 1 } }
