Interface used to described an object with string keys corresponding to values of type T

Converts a plain object to a Map instance

const map = objectToMap({ a: "b", c: "d"});

Merges two or more maps, overwriting values with the same key. Last value in wins.

const m1 = new Map();
const m2 = new Map();
const m3 = new Map();
const m4 = new Map();

const m = mergeMaps(m1, m2, m3, m4);
