Lecture 22: Memoization. The MDN Docs have a great article if you haven't worked with JSON before. Because JavaScript objects behave like associative arrays, they are ideal candidates to act as caches. The complete modules available there are as follows: A closure is the combination of a function and the lexical environment within which that function was declared. So, if you calculate the value of factorial(1) you can store the return value 1 and the same action can be done in each execution. All about the JavaScript programming language!

If the data is present, then it can be returned, without executing the entire function. Thanks to JavaScript awesome language design we are able to return functions from functions, so we will use this “feature” to return a function which has a cache property inside itself.

This is probably the easiest solution if you can set the contentType yourself. So, when you run the factorial(100), execution may take a while the first time, but the second time, runtime will be reduced. Primitive data types are referenced by value. Functions created with the Function constructor do not create closures to their creation contexts; they always are created in the global scope. You can spend a significant amount of time trying to optimize your code for caching, however, techniques such as memoization encourage you to reevaluate your code in order to determine if the time put in as well as the extra memory used by the process is worth the effort.
