toArray() function

Takes item from Iterable/AsyncIterable and returns an array. It is recommended to use pipe together.

Signature:

declare function toArray<A extends Iterable<unknown> | AsyncIterable<unknown>>(iter: A): ReturnArrayType<A>;

Example

pipe(
 [1, 2, 3, 4, 5],
 map(a => a + 10),
 filter(a => a % 2 === 0),
 toArray,
); // [12, 14]

await pipe(
 Promise.resolve([1, 2, 3, 4, 5]),
 map(a => a + 10),
 filter(a => a % 2 === 0),
 toArray,
); // [12, 14]

// if you want to use asynchronous callback
await pipe(
 Promise.resolve([1, 2, 3, 4, 5]),
 toAsync,
 map(async (a) => a + 10),
 filter(a => a % 2 === 0),
 toArray,
); // [12, 14]

// with toAsync
await pipe(
 [
   Promise.resolve(1),
   Promise.resolve(2),
   Promise.resolve(3),
   Promise.resolve(4),
   Promise.resolve(5)
 ],
 toAsync,
 map((a) => a + 10),
 filter((a) => a % 2 === 0),
 toArray
);
