# memz [![JSR](https://jsr.io/badges/@korkje/memz)](https://jsr.io/@korkje/memz)

Wrap any function with a cache.

```ts

import memoize from "jsr:@korkje/memz";

const add = memoize((a: number, b: number) => a + b);

```

Recursion:

```ts

const fib = memoize((n: number): number => {

    if (n < 2) {

        return n;

    }

    return fib(n - 2) + fib(n - 1);

});

```

Initial cache:

```ts

// Start with 2 and 1, i.e. create the Lucas sequence.

const cache = { "[0]": 2, "[1]": 1 };

const fib = memoize(

    (n: number): number => fib(n - 2) + fib(n - 1),

    { cache },

);

```

By default, cache keys are arguments serialized to JSON, hence the `"[0]"` and `"[1]"` keys above.

Custom cache keys:

```ts

const fib = memoize(

    (n: number): number => fib(n - 2) + fib(n - 1),

    { keyFn: n => n },

);

```
