make-integer-sequence

A function that returns an integer sequence in a iterator-like fashion.

makeIntegerSequence(startingAt = 0, endingAt = Number.MAX_SAFE_INTEGER, startOverWhenAtEnd = false)

This is the default export of the library.

It takes a three optional arguments:

1. The starting value of the sequence. Defaults to 0.
2. The ending value of the sequence. Defaults to Number.MAX_SAFE_INTEGER.
3. Whether to start the sequence over when the ending value is reached. Defaults to false, which throws an error.

It returns a function that, when called, returns the next value in the sequence, e.g.:

import makeIntegerSequence from 'make-integer-sequence'

const getNextInteger = makeIntegerSequence()

console.log(getNextInteger()) // 0
console.log(getNextInteger()) // 1
console.log(getNextInteger()) // 2

integerIterator(startingAt = 0, endingAt = Number.MAX_SAFE_INTEGER, startOverWhenAtEnd = false)

It has the same signature as makeIntegerSequence.

It returns the underlying iterator instead of the convenience function.

import { integerIterator } from 'make-integer-sequence'

const integers = integerIterator(2, 4)

for (const i of integers) {
  console.log(i) // 2, 3
}
