import { map } from "https://deno.land/x/aitertools@0.3.1/mod.ts";
Transforms every element of the iterable source into a new iterable.
import { map } from "./map.ts";
import { count } from "./infinite.ts";
const iterable = map((v: number) => v * 2, count());
for await (const value of iterable) console.log(value);
The above example will print the following and keep going forever:
0
2
4
6
(...)
The fn function can take an additional argument, which is the index of the
element in the iterable.
import { map } from "./map.ts";
const iterable = map(
(v: string, i: number) => `${i}. ${v.toUpperCase()}`,
["foo", "bar", "baz", "qux"]
);
for await (const value of iterable) console.log(value);
The above example will print the following 4 lines:
0. FOO
1. BAR
2. BAZ
3. QUX
Transforms every element of the iterables into a new single iterable. If iterable sources are of different lengths, the resulting iterable will be of the same length as the shortest iterable.
import { map } from "./map.ts";
import { count } from "./infinite.ts";
const iterable = map(
(s: string, n: number) => `${s} ${n}`,
["foo", "bar", "baz", "qux"],
count()
);
for await (const value of iterable) console.log(value);
The above example will print the following 4 lines:
foo 0
bar 1
baz 2
qux 3
The fn function can take an additional argument, which is the index of the
element in the iterable.
import { map } from "./map.ts";
import { count } from "./infinite.ts";
const iterable = map(
(s: string, n: number, i: number) => `${i}. ${s} ${n}`,
["foo", "bar", "baz", "qux"],
count(0, 5)
);
for await (const value of iterable) console.log(value);
The above example will print the following 4 lines:
0. foo 0
1. bar 5
2. baz 10
3. qux 15
Parameters
A function that takes elements of the same position in the sources and returns a single transformed element. It can be either async or sync.
Transforms every element of the iterables into a new single iterable. If iterable sources are of different lengths, the resulting iterable will be of the same length as the shortest iterable.
Parameters
A function that takes elements of the same position in the sources and returns a single transformed element. It can be either async or sync.
The first iterable to transform with fn.
Its each element will be passed as the first argument to
fn.
Transforms every element of the iterables into a new single iterable. If iterable sources are of different lengths, the resulting iterable will be of the same length as the shortest iterable.
Parameters
A function that takes elements of the same position in the sources and returns a single transformed element. It can be either async or sync.
The first iterable to transform with fn.
Its each element will be passed as the first argument to
fn.
The second iterable iterable to transform with fn.
Its each element will be passed as the second argument to
fn.
Transforms every element of the iterables into a new single iterable. If iterable sources are of different lengths, the resulting iterable will be of the same length as the shortest iterable.
Parameters
A function that takes elements of the same position in the sources and returns a single transformed element. It can be either async or sync.
The first iterable to transform with fn.
Its each element will be passed as the first argument to
fn.
The second iterable iterable to transform with fn.
Its each element will be passed as the second argument to
fn.
The third iterable iterable to transform with fn.
Its each element will be passed as the third argument to
fn.
