Safely accessing deeply nested values ⚡️

import { set, get } from 'propx';
const obj = {
    a: 1,
    b: 2,
    c: { d: { e: { f: 3 } } },
    g: undefined
};

console.log(get(obj, 'c.d.e.f', ''))
//-> 3

console.log(set(obj, 'g.x.y.z', ['hey']))
/* -> {
    a: 1,
    b: 2,
    c: { d: { e: { f: 3 } } },
    g: { x: { y: { z: [ 'hey' ] } } }
}
