About this version
compositeKey & compositeSymbol implementation
Allows for multiple values to be "joined" together and used as a single key.
Returns a frozen object that can be used as a reference in place of the original arguments
The object can be used as a key in a WeakMap, or Map. The object can also be used in a WeakSet.
import { compositeKey } from "@virtualstate/composite-key";
const map = new WeakMap();
const array = [1, 2, 3];
map.set(compositeKey(array, 1), "Value");
map.get(compositeKey(array, 1)); // "Value"
map.get(compositeKey(array, 2)); // undefinedReturns a symbol that can be used as a reference in place of the original arguments.
The symbol can be used in most places, including keys of objects, and Maps. The symbol can also be used in a Set.
import { compositeSymbol } from "@virtualstate/composite-key";
const map = new Map();
const array = [1, 2, 3];
map.set(compositeSymbol(array, 1), "Value");
map.get(compositeSymbol(array, 1)); // "Value"
map.get(compositeSymbol(array, 2)); // undefinedCreates an isolated version of compositeKey
import { createCompositeKey } from "@virtualstate/composite-key";
const compositeKey = createCompositeKey();
const array = [1, 2, 3];
compositeKey(array, 1); // An objectCreates an isolated version of compositeSymbol
import { createCompositeSymbol } from "@virtualstate/composite-key";
const compositeSymbol = createCompositeSymbol();
const array = [1, 2, 3];
compositeSymbol(array, 1); // A symbolDetails
