// 6

Installation

CLI

npx atmx add helper iterate

Manually

Copy and paste the following method into @/utils/helpers/iterate.ts:

/**
* Like a reduce but does not require an array. Only need a number and
* will iterate the function as many times as specified.
*
* NOTE: This is NOT zero indexed. If you pass count=5 you will get 1,
* 2, 3, 4, 5 iteration in the callback function.
*
* @example
* iterate(3, (total, i) => total + i, 0)
* // 6

initValue: T,
): T {

for (let i = 1; i <= count; i++) {
value = func(value, i);
