debounce-throttle-javascript

Debouce

Debounce execution of a function. Debouncing, unlike throttling, guarantees that a function is only executed a single time, either at the very beginning of a series of calls, or at the very end.

Throttle

Throttle execution of a function. Especially useful for rate limiting execution of handlers on events like resize and scroll.

Install

npm install debounce-throttle-javascript

Usage

`debounce`

const { debounce } = require("debounce-throttle-javascript");
/**
 * Using debounce() function
 * Param 1: Callback function to execute for debouncing behaviour eg. functionToExecute()
 * Parram 2: Time in milliseconds or debouncing interval eg. 500
 */
const debounceFunction = debounce(functionToExecute, 500);

`throttle`

const { throttle } = require("debounce-throttle-javascript");
/**
 * Using throttle() function
 * Param 1: Callback function to execute for throttling behaviour eg. functionToExecute()
 * Parram 2: Time in milliseconds or throttling interval eg. 300
 */
const throttleFunction = throttle(functionToExecute, 300);

API

throttle(callback, delay)

Returns: Function

Throttle execution of a function. Especially useful for rate limiting execution of handlers on events like resize and scroll.

delay

Type: Number

A zero-or-greater delay in milliseconds. For event callbacks, values around 100 or 250 (or even higher) are most useful.

callback

Type: Function

A function to be executed after delay milliseconds. The this context and all arguments are passed through, as-is, to callback when the throttled-function is executed.
