I'm using reselect for memoized selectors in a redux environment. Note in the readme for reselect that these selectors are composable - that is, one selector can be used by another. Here are my selectors:  import { createSelector } from 'rese...
Context.  Memoization is a functional technique operating over recursive functions with overlapping invocations aiming to optimize time performance by using an internal cache that remembers previous results with already used parameters. A typical use...
Could memoization be considered as a design pattern or is simply a method for caching?   https://addyosmani.com/blog/faster-javascript-memoization/...
So I have this little snippet:  const useTest = (callbackFunc) => {     const user = useSelector(selector.getUser); //  a value from store      useEffect(() => {       if (user.id === 1) {          callbackFunc()       }     }, [callbackFunc, u...
I want to cache the jQuery AJAX response so that I don't need to make the network call again.  Below is my JS code:  $(".btn").on("click", function(){     var id = $(this).data("id");     var url = "https://alert-carpe...

I have written a function for partitioning a number:  var combinations = function (i) {     var mem = [];     function inner(n, r, m) {         for (var k = m; k <= n; k++) {             if (k == n) {                 r.push(k);                 mem...
var fibo = function (x) {   console.log(x);   if (x === 1) return 1;   if (x === 2) return 2;   return fibo(x - 1) + fibo(x - 2); };  // fibo = _.memoize(fibo); var fibom = _.memoize(fibo); console.log(fibom(5)); <script src="https://cdn.jsd...
I have a large data collection that I frequently query by first applying a filter to it. I want to cache and reuse the results of the different filter functions I use because this part can be expensive. Here's a rough simulation of this:  const a...
