Generators Are Like Arrays

In all the discussions about ES6 one thing is bugging me. I'm picking one random comment here from this io.js issue but it's something that comes up over and over again:

There's sentiment from one group that Node should have full support for Promises. While at the same time another group wants generator syntax support (e.g. var f = yield fs.stat(...)).

People keep putting generators, callbacks, co, thunks, control flow libraries, and promises into one bucket. If you read that list and you think "well, they are all kind of doing the same thing", then this is to you.

About Lodash, how it works (forEach example)

Hi!

About Lodash's forEach function, and Lodash in general…

I told you that it "abstracts away from you the chore (and complexity) of looping", so that you can focus on what really matters for your application: the collection you want to iterate through, and the piece of logic you wish to be applied for each item.

You use forEach like this:

// You first define "the collection you want to iterate through":

Clean up your Vue modules with ES6 Arrow Functions

Recently when refactoring a Vue 1.0 application, I utilized ES6 arrow functions to clean up the code and make things a bit more consistent before updating to Vue 2.0. Along the way I made a few mistakes and wanted to share the lessons I learned as well as offer a few conventions that I will be using in my Vue applications moving forward.

The best way to explain this is with an example so lets start there. I'm going to throw a rather large block of code at you here, but stick with me and we will move through it a piece at a time.

<script>

// require vue-resource...

new Vue({
let webpack = require('webpack');
let path = require('path');
module.exports = {
entry: {
app: './resources/assets/js/app.js',
vendor: ['vue', 'axios']
},
output: {

Polling in JS with an async ajax call that returns a promise ( modified from: https://davidwalsh.name/javascript-polling )
// The polling function
function poll(fn, timeout, interval) {
var endTime = Number(new Date()) + (timeout || 2000);
interval = interval || 100;
var checkCondition = function(resolve, reject) {
var ajax = fn();
// dive into the ajax promise
ajax.then( function(response){
// If the condition is met, we're done!

Strings

String.prototype.*

None of the string methods modify this – they always return fresh strings.

  • charAt(pos: number): string ES1

    Returns the character at index pos, as a string (JavaScript does not have a datatype for characters). str[i] is equivalent to str.charAt(i) and more concise (caveat: may not work on old engines).
