Give eachr an item to iterate (array, object or map) and an iterator, then in return eachr gives iterator the value and key of each item, and will stop if the iterator returned false.
Give eachr an item to iterate (array, object or map) and an iterator, then in return eachr gives iterator the value and key of each item, and will stop if the iterator returned false.
Eachr accepts an array, object, or map. The iterator is bound to the list, and receives three arguments: the value, key, and list.
// Prepare
const eachr = require('eachr')
const arr = ['first', 'second', 'third']
const obj = { a: 'first', b: 'second', c: 'third' }
const map = new Map([
['a', 'first'],
['b', 'second'],
['c', 'third'],
])
function iterator(value, key) {
console.log({ value: value, key: key })
if (value === 'second') {
console.log('break')
return false
}
}
// Cycle Array
eachr(arr, iterator)
// {'value': 'first', 'key': 0}
// {'value': 'second', 'key': 1}
// break
// Cycle Object
eachr(obj, iterator)
// {'value': 'first', 'key': 'a'}
// {'value': 'second', 'key': 'b'}
// break
// Cycle Map
eachr(map, iterator)
// {'value': 'first', 'key': 'a'}
// {'value': 'second', 'key': 'b'}
// break
