I'm wondering if there is a way to implement a generic "memoize" functional (as in a function with a function as input and a function as output, as python's decorators) capable of handling also cps-style functions.  for a normal funct...
I have something like this:    function main() {   function create_node() {     console.log("create_node")       (function() {         var memo;         console.log(memo);          function f() {           var value;           console.log(val...
Summary: Is there a faster way to hash objects than JSON.stringify?  Details: I have a Ruby and JavaScript library (NeatJSON) that provides pretty-printing of JavaScript values. I recently fixed a problem where deeply-nested objects caused O(n!) perf...
Beginner in JS :) needs an explanation of code piece from Crockford's book, section 4.15:    var memoizer = function (memo, fundamental) {     var shell = function (n) {         var result = memo[n];         if (typeof result !== 'number'...
...or are there better ways to implement a Memoization?  Function.memoize = function(callableAsString)     {     var r = false, callable, code;     try         {         callable = eval(callableAsString);         if (typeof callable == "function&...
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...
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 noticed something peculiar when attempting to speed up a recursive function. When I made the object I was employing for memoization an argument to be passed to the function rather than a global variable, the code execution became considerably slowe...
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...
