setTimeout

function setTimeout(timeout: number, cb: () => unknown): () => void

A wrapper for globalThis.setTimeout, with the following differences:

• Better order of parameters.
• No function parameters binding.
• The return value is the function to cancel the timer.

setSchedule

function setSchedule(timestamp: number, cb: () => unknown): () => void

setInterval

function setInterval(timeout: number, cb: () => unknown): () => void

A wrapper for globalThis.setInterval, with the following differences:

• Better order of parameters.
• No function parameters binding.
• The return value is the function to cancel the timer.

setImmediate

function setImmediate(cb: () => unknown): () => void

A wrapper for globalThis.setImmedidate, with the following differences:

• No function parameters binding.
• The return value is the function to cancel the timer.

When globalThis.setImmediate does not exist, it will fall back to setTimeout(cb, 0).

setTimeoutLoop

function setTimeoutLoop(timeout: number, cb: () => unknown): () => void

Create an interval timer using the nested setTimeout, which does not schedule the next run until the callback function returns.

The return value is the function to cancel the timer.

setDynamicTimeoutLoop

function setDynamicTimeoutLoop(timeout: number, cb: () => unknown): () => void

Create an interval timer using the nested setTimeout, which does not schedule the next run until the callback function returns, and dynamically adjusts the interval time based on the execution time of the callback function.

The return value is the function to cancel the timer.

calculateExponentialBackoffTimeout

function calculateExponentialBackoffTimeout({
  baseTimeout
, retries
, maxTimeout = Infinity
, factor = 2
, jitter = true
}: {
  baseTimeout: number
  retries: number
  maxTimeout?: number
  factor?: number
  jitter?: boolean
}): number
