Variable: entries()

const entries: {<Key, Value>(object): Iterable<[Key, Value]>; <Key, Value>(object): Iterable<[Key, Value]>; }

Defined in: generators.d.ts:188

Returns an iterable containing the entries of object.

This differs from Map.prototype.entries in that the returned iterable can be iterated multiple times and differs from Object.entries in that the returned iterable is opaque.

<Key, Value>(object): Iterable<[Key, Value]>

Type Parameters​

Key​

Call Signature​

<Key, Value>(object): Iterable<[Key, Value]>

Type Parameters​

Value​

Value

Parameters​

object​

Readonly<Record<Key, Value>>

Example​

import { entries, pipe, reduce, toArray } from 'lfi'

console.log(
  pipe(
    entries([`sloth`, `lazy`, `sleep`]),
    reduce(toArray()),
  ),
)
//=> [
//=>   [ 0, 'sloth' ],
//=>   [ 1, 'lazy' ],
//=>   [ 2, 'sleep' ]
//=> ]

console.log(
  pipe(
    entries({
      sloth: 1,
      lazy: 2,
      sleep: 3,
    }),
    reduce(toArray()),
  ),
)
//=> [
//=>   [ 'sloth', 1 ],
//=>   [ 'lazy', 2 ],
//=>   [ 'sleep', 3 ]
//=> ]

console.log(
  pipe(
    entries(
      new Map([
        [`sloth`, 1],
        [`lazy`, 2],
        [`sleep`, 3],
      ]),
    ),
    reduce(toArray()),
  ),
)
//=> [
//=>   [ 'sloth', 1 ],
//=>   [ 'lazy', 2 ],
//=>   [ 'sleep', 3 ]
//=> ]
