A React hook for throttling setState and other callbacks.

Quick Start

import {useThrottle, useThrottleCallback} from '@react-hook/throttle'

const Component = props => {
  // at a basic level, used just like useState
  const [value, setValue] = useThrottle('initialValue')
}

const useMyCallback = (initialState, wait, leading) => {
  // this is the same code useThrottle() uses to throttle setState
  const [state, setState] = useState(initialState)
  return [state, useThrottleCallback(setState, wait, leading)]
}
