// Problem
const Foo = function(a) {
  function bar() {
	return a;
  }
  this.baz = function() {
	return a;
  };
};

Foo.prototype.biz = function() {
  return a;
};

const f = new Foo(7);

f.bar(); // ?
f.baz(); // ?
f.biz(); // ?

  • Follow-up:
    let memoizedFib = memoize(fib)
    memoizedFib(1000) ==> result is computed
    memoizedFib(1000) ==> no re-computation, the previous result has been cached and this call simply returns the value.
    Write a generalised memoize fn.
