Usage

debounce:

const debounceWrap = require('debounce-wrap')
const debounce = debounceWrap(input, { wait: 100 })

function input(a) {
  console.log(a)
}

debounce('hi') 
debounce('hi') 
// log 'hi' once after 100ms.

excute immediately, then debounce:

const debounceWrap = require('debounce-wrap')
const debounce = debounceWrap(input, { wait: 100, first: true })

function input(a) {
  console.log(a)
}

debounce('hi') // log 'hi' immediately, no delay.
debounce('hi2') // log 'hi2' after 100ms.

bind this:

const debounceWrap = require('debounce-wrap')
const debounce = debounceWrap(function () {
  console.log(this === window)
}, { wait: 100 })

window.onresize = debounce

// log 'true' when resizing the window

cancel debounce:

const debounceWrap = require('debounce-wrap')
const debounce = debounceWrap(input, { wait: 100, first: true })

function input(a) {
  console.log(a)
}

debounce('hi')
debounce('hi2')

debounce.cancel() // cancel `debounce('hi2')`, no log.

setTimeout(function () {
  debounce('hi3') // log 'hi3' after 100ms
}, 300)
