# bimap
A simple and tiny bi-directional map that extends ES2015's Map.
BiMap can be operated with the same interface as Map, and you can get an inverted BiMap with `inverse`.
```ts
// cjs
const { BiMap, WeakBiMap } = require("@rizzzse/bimap");
// esm
import { BiMap, WeakBiMap } from "@rizzzse/bimap";
const bimap = new BiMap([["key", "value"]]);
bimap.get("key"); // === "value"
bimap.inverse.get("value"); // === "key"
bimap.set("key2", "value");
bimap.has("key"); // === false
bimap.get("key2"); // === "value"
bimap.inverse.get("value"); // === "key2"
```
```ts
class MyBiMap extends BiMap {
declare readonly inverse: MyBiMap;
myMethod() {
// ...
}
}
```
