Function repeat

Generates values from produce with a time delay. produce can be a simple function that returns a value, an async function, or a generator. If produce returns undefined, generator exits.

Example

Produce a random number every 500ms

const randomGenerator = repeat(() => Math.random(), 500);
for await (const r of randomGenerator) {
 // Random value every 1 second
 // Warning: does not end by itself, a `break` statement is needed
}
Copy

Example

Return values from a generator every 500ms

import { repeat } from 'https://unpkg.com/ixfx/dist/flow.js'
import { count } from 'https://unpkg.com/ixfx/dist/numbers.js'
for await (const v of repeat(count(10), { fixed: 1000 })) {
 // Do something with `v`
}
Copy

Options allow either fixed interval (wait this long between iterations), or a minimum interval (wait at least this long). The latter is useful if produce takes some time - it will only wait the remaining time or not at all.

If the AbortSignal is triggered, an exception will be thrown, stopping iteration.
