import { type array } from "https://deno.land/x/fun@v2.0.0-alpha.6/mod.ts";
const { array } = array;
Specifies ReadonlyArray as a Higher Kinded Type, with covariant parameter A corresponding to the 0th index of any substitutions.
import { type array } from "https://deno.land/x/fun@v2.0.0-alpha.6/mod.ts";
const { array } = array;
This type alias extracts the inner type of a ReadonlyArray.
import { array } from "https://deno.land/x/fun@v2.0.0-alpha.6/mod.ts";
const { array } = array;
The canonical implementation of Functor for ReadonlyArray. It contains the method map.
import { array } from "https://deno.land/x/fun@v2.0.0-alpha.6/mod.ts";
const { array } = array;
Create a NonEmptyArray from a variadic number of arguments.
Examples
Example 1
Example 1
import * as A from "./array.ts";
const result = A.array(1, 2, 3, 4); // [1, 2, 3, 4]
Parameters
Given a Predicate or Refinement, apply the predicate or refinement to every value in an array, removing (and refining) the elements that the predicate or refinement return false for.
Examples
Example 1
Example 1
import * as A from "./array.ts";
import { pipe } from "./fn.ts";
const result = pipe(
A.array(1, 2, 3, 4, 5, 6),
A.filter(n => n % 2 === 0),
); // [2, 4, 6]
Type Parameters
Parameters
Partition a ReadonlyArray into two ReadonlyArrays using a predicate or refinement to do the sorting. If the predicate or refinement returns true for a value, the value is pushed into the first array in a Pair, otherwise it is pushed into the second array in a pair.
Examples

Example 1
import * as A from "./array.ts";
import { pipe } from "./fn.ts";
const result = pipe(
A.range(10, 1), // [1, 2, 3, ..., 10]
A.partition(n => n % 2 === 0),
); // Pair<[2, 4, 6, 8, 10], [1, 3, 5, 7, 9]>
