Callbag debounce

Debounce operator for Callbag

Install

Example

Debounces the scroll event and runs the expensiveFunction only when there is a 60ms pause.

``javascript
const { fromEvent, forEach, pipe } = require("callbag-basics");
import { debounce } from "callbag-debounce";

pipe(
fromEvent(document, "scroll"),
debounce(60),
forEach(expensiveFunction)
);
`

Changelog

BREAKING CHANGE:

- Last value is flushed even if the stream is receiving a terminate signal before the value has been debounced (fixes #12)

Before

`js
pipe(
of(42),
debounce(1000),
subscribe(console.log)
)
// Terminate without logging anything
`

After

`js
pipe(
of(42),
debounce(1000),
subscribe(console.log)
)
// log: 42
// Then terminate
`

BREAKING CHANGE:

- Timer is cleared when stream is terminated by sink (see #13)

$3

- error (t === 2 && d !== undefined) signals are sent right away (previously they were delayed according to the wait parameter);
- complete (t === 2 && d === undefined) signals are sent when the last value is debounced (previously they were debounced according to the wait parameter).

$3

codebase migrated to TypeScript.
The module needs to be imported via a named import

`javascript
