useThrottleFn
Throttle execution of a function. Especially useful for rate limiting execution of handlers on events like resize and scroll.
Throttle is a spring that throws balls: after a ball flies out it needs some time to shrink back, so it cannot throw any more balls unless it's ready.
Usage
import { useThrottleFn } from '@vueuse/core'
const throttledFn = useThrottleFn(() => {
// do something, it will be called at most 1 time per second
}, 1000)
useEventListener(window, 'resize', throttledFn)

Type Declarations
/**
* Throttle execution of a function. Especially useful for rate limiting
* execution of handlers on events like resize and scroll.
*
* @param fn 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.
* @param ms A zero-or-greater delay in milliseconds. For event callbacks, values around 100 or 250 (or even higher) are most useful.
* (default value: 200)
*
* @param [trailing] if true, call fn again after the time is up (default value: false)
*
* @param [leading] if true, call fn on the leading edge of the ms timeout (default value: true)
*
* @param [rejectOnCancel] if true, reject the last call if it's been cancel (default value: false)
*
* @return A new, throttled, function.
*
* @__NO_SIDE_EFFECTS__
