JavaScript. The Core: 2nd Edition – ds.laboratory

The Core overview lecture, devoted to ECMAScript programming language and core components of its runtime system. Audience: experienced programmers, professionals. The first edition of the article covers generic aspects of JS language, using abstractions mostly from the ES3 spec, with some references to the appropriate changes in ES5 and ES6+. Starting since ES2015, the specification changed descriptions and structure of some core components, introduced new models, etc. And in this edition we focus on the newer abstractions, updated terminology, but still maintaining the very basic JS structures which stay consistent throughout the spec versions.

The Promise of a Burger Party - Mariko Kosaka

It needed to be asynchronous to access external data, I said "well, let's use fetch() in code... umm... " while I paused to remember fetch API, the person I was talking to said, "It returns a promise". My brain froze, and I said: "I honestly don't know what you mean... " Functional Programming By Example. While chatting in a CodeNewbie Slack channel I realized that the question of what functional programming is in relation to object oriented programming is a question that comes up a lot and is an area of great confusion.

Functional Programming By Example

For this reason, I wanted to write an article to hopefully help clear up this confusion, even if just for a little. What I came up with was 11 different versions of the same program. The program reads in a file containing some text, breaks the text into individual words, counts them up, and displays the top 10 words that were used in the text.

We all remember the dreaded XMLHttpRequest we used back in the day to make requests, it involved some really messy code, it didn't give us promises and let's just be honest, it wasn't pretty JavaScript, right?

How to Use the JavaScript Fetch API to Get Data

Maybe if you were using jQuery, you used the cleaner syntax with jQuery.ajax(). Well JavaScript has it's own built-in clean way now. Along comes the Fetch API a new standard to make server request jam-packed with promises and all those things we learned to love over the years. How do we use the Fetch API? In a very simple manner all you really do is call fetch with the URL you want, by default the Fetch API uses the GET method, so a very simple call would be like this: fetch(url) .then(function() { }).catch(function() { });

In Wicked Detail - Matt Greer. I’ve been using promises in my JavaScript code for a while now. They can be a little brain bending at first. I now use them pretty effectively, but when it came down to it, I didn’t fully understand how they work. This article is my resolution to that.

If you stick around until the end, you should understand promises well too. We will be incrementally creating a promise implementation that by the end will mostly meet the Promises/A+ spec, and understand how promises meet the needs of asynchronous programming along the way.
