☰std/function/memoizeShallow

Memoizes the function result so it is not computed for the same parameters. Uses shallow equality.

Type signature

<TResult>(f: (...xs: unknown[]) => TResult) => (...args: unknown[]) => TResult

Examples

const f = ({ x }) => {
  console.log(x);
  return x + 1;
};

const memoized = memoizeShallow(f);

memoized({ x: 5 });
memoized({ x: 5 });
memoized({ x: 5 });
memoized({ x: 3 });

Try in REPL
