utility methods for looping through objects

why?

I got tired of typing Object.keys(object).forEach(function(key) { //do something with object[key] })

examples

import { forEachKeys, filterKeys, mapKeys, everyKeys, someKeys, reduceKeys, findKeys } from 'object-looper'

forEachKeys(obj, (key, value, index) => {
  //do something
})

const obj = {
  key1: 'test',
  key2: 'test2'
}
const filtered = filterKeys(obj, (key, value, index) => {
  return value === 'test'
})

//filtered is { key1: 'test' }

const obj = {
  key1: 'test',
  key2: 'test2'
}
const mapped = mapKeys(obj, (key, value, index) => {
  return { [key]: value + 'map'}
})}

//mapped is now { key1: 'testmap', key2: 'test2map' }

const obj = {
  key1: 1,
  key2: 2
}
const isSmallEnough = everyKeys(obj, (key, value, index) => {
  return value < 10
})

//isSmallEnough is true

const obj = {
  key1: 1,
  key2: 11
}
const isSmallEnough = someKeys(obj, (key, value, index) => {
  return value < 10
})

//isSmallEnough is true

const obj = {
  key1: 1,
  key2: 11
}
const result = reduceKeys(obj, (prevKey, prevValue, currKey, currValue, index) => {
  return prevValue + currValue
})

//result is 11

const obj = {
  key1: 1,
  key2: 11
}
const result = findKeys(obj, (key, value, index) => {
  return value === 1
})

//result is { key1: 1 }

modules

you can also import each utility as its own module

import forEachKeys from 'object-looper/forEachKeys'

where is x method from array?

This initial release are methods that I think cover the majority of the use cases. please feel free to pull-request with added looping fun!
