Throttle Fn

createThrottleFn()

Wraps a plain function in a throttled callable that also acts as a subscribable.

The first call fires immediately. Subsequent calls within the wait window are batched — only the last one fires when the interval elapses. The return value of the wrapped function becomes the current state, notifying subscribers.

Examples

import { createThrottleFn } from 'seitu'

const log = createThrottleFn((msg: string) => console.log(msg), 300)
log.subscribe(result => console.log('result:', result))
log('hello') // fires immediately
log('world') // throttled — fires after 300ms
log.get() // latest return value (undefined until first call)
