Memoized bind implementation and example

memoized-bind-example.js

function memoizedBind(fn, ...args) {
  // Memoize the bind call (with cache size 1).
  if (!areArgumentsShallowlyEqual(fn.__lastArgs, args)) {
    fn.__lastResult = fn.bind.apply(fn, args);
    fn.__lastArgs = args;
  }
  return fn.__lastResult;
}

// ======================================================
// Before transform

myFn.bind(this, foo, bar);

// ======================================================
// After transform

memoizedBind(myFn, this, foo, bar);
