How can I memoize a promise-based function? Would straightforward memoization of the function suffice? function foo() { return new Promise((resolve, reject) => { doSomethingAsync({ success: resolve, fail: reject }); }); }; Would...
Given an array or object with n keys, I need to find all combinations with length x. Given X is variable. binomial_coefficient(n,x). Currently I'm using this: function combine(items) { var result = []; var f = function(prefix, items) {...
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'...
Promises are my preferred way of managing my asynchronous code in Javascript. Memoize (memoizee on npm) is a Javascript library for easily caching & pre-fetching results of functions. Ideally I want to combine the best of both, and have the abil...
I'm working with some government data published via Socrata's SODA api. This API provides a way to retrieve rows via a REST call. The API allows limited parameterization of the query - basically you can do a full text search, and nothing els...
Let's say I have this code (fiddle) intended to memoize modules: var chat = { // Create this closure to contain the cached modules module: function() { // Internal module cache. var modules = {}; console.log('in module:',...
I am stumped with this memoize problem. I need to create a function that will check to see if a value has already been calculated for a given argument, return the previous result, or run the calculation and return that value. I have spent hours on...
