### zipObject
|
|
|
|
Given an array of valid property identifiers and an array of values, return an object associating the properties to the values.
|
|
|
|
Since an object can have undefined values but not undefined property pointers, the array of properties is used to decide the structure of the resulting object using `Array.reduce()`.
|
|
|
|
```js
|
|
const zipObject = ( props, values ) => props.reduce( ( obj, prop, index ) => ( obj[prop] = values[index], obj ), {} )
|
|
// zipObject(['a','b','c'], [1,2]) -> {a: 1, b: 2, c: undefined}
|
|
// zipObject(['a','b'], [1,2,3]) -> {a: 1, b: 2}
|
|
```
