Function: entries()

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.

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 ]
//=> ]
