setTimeout on a memoized function

Question

Assuming ES5, I want to do something like this.

var memoizedFunc = (function(params) {
  var cache = {};
  var mem = function(params) {
    //Do some stuff involving the cache
    return someResult;
  }
  return mem;
}());
setTimeOut(memoizedFunc(params), 2000);

The timeout isn't working on the mem function however, how could I implement this?

Answer 1

传递函数引用而不是其执行结果

setTimeOut(function(){memoizedFunc(params)}, 2000);
