Examples

Creating a new object from arrays of keys and values

import { objCreate } from '@superutils/core'

const keys = ['a', 'b', 'c']
const values = [1, 2, 3]
const newObj = objCreate(keys, values)
console.log(newObj)
// newObj is { a: 1, b: 2, c: 3 }

Merging into an existing object

import { objCreate } from '@superutils/core'

const existingObj = { a: 0, d: 4 }
const keys = ['b', 'c']
const values = [2, 3]
const newObj = objCreate(keys, values, existingObj)
console.log(newObj)
// existingObj is now { a: 0, d: 4, b: 2, c: 3 }
