bury(object, keypath, value)
import bury from 'bury';
let obj = {
a: {
b: {
c: 1
d: undefined
e: null
}
}
};
//use string dot notation for keys
bury(obj, 'a.b.c', 2) === 2;
//or use an array key
bury(obj, ['a', 'b', 'c'], 2) === 2;
//returns undefined if the full key path does not exist
bury(obj, 'a.b.c.f', "foo") === undefined;https://github.com/kalmbach/bury/blob/master/test.js
