### Object from key-value pairs
Use `map()` to create objects for each key-value pair, combine with `Object.assign()`.
Use `Array.reduce()` to create and combine key-value pairs.
```js
const objectFromPairs = arr =>
Object.assign(...arr.map( v => {return {[v[0]] : v[1]};} ));
const objectFromPairs = arr => arr => arr.reduce((a,b) => { a[b[0]] = b[1]; return a;}, {});
```
