I've read over several examples of code using JavaScript generators such as this one. The simplest generator-using block I can come up with is something like: function read(path) { return function (done) { fs.readFile(path, "f...I've got this recursive generator var obj = [1,2,3,[4,5,[6,7,8],9],10] function *flat(x) { if (Array.isArray(x)) for (let y of x) yield *flat(y) else yield 'foo' + x; } console.log([...flat(obj)])...This question already has answers here:...
The following implements a control flow wrapper co enabling asynchronous code to be delineated only by the yield keyword. Is this basically what async/await does under the hood in ESwhatever? co(function*() { console.log('...'); y...I've been very excited about Node JS for awhile. I finally decided to knuckle down and write a test project to learn about generators in the latest Harmony build of Node. Here is my very simple test project: https://github.com/kirkouimet/projec...
I have constructed a function which iterates through a Generator containing both synchronous code and Promises: module.exports = { isPromise (value) { return typeof value === 'object' && value !== null && &#...This question already has answers here:...
I'm trying to create a promise-wrapper using generator so that I can do: var asyncResult = PromiseWrapper( $.ajax( ... ) ); So far, I've been trying with: function PromiseWrapper(promise){ return function *wrapper(promise){ pr...When passing parameters to next() of ES6 generators, why is the first value ignored? More concretely, why does the output of this say x = 44 instead of x = 43: function* foo() { let i = 0; var x = 1 + (yield "foo" + (++i)); conso...Does ES6's support for tail call optimization cover tail calls in generators? Suppose I have this generator for integers >= 0: var nums = function* (n) { n = n || 0; yield n; yield* nums(n + 1); }; Currently, in Chrome and Fire...©2020 All rights reserved.
