Making QR codes with cloud functions • tommorris.org

Tom makes an endpoint for generating QR codes so you don’t have to rely on the Google Charts API.

He also provides a good definition of “serverless”:

Now, serverless is a very silly buzzword dreamed up by someone from the consultant class who love coming up with terrible names, so I promise I won’t use it any further. Your code obviously run on a server. It just means it runs on a server someone else manages.

Amazon call it a ‘Lambda Function’. Google call it a ‘Cloud Function’. Microsoft Azure call it simply a ‘Function’. But none of those are very descriptive, because, well, anyone who writes any kind of programming language generally writes functions pretty much all the time in much the same way as anyone who writes English writes paragraphs, and we don’t call our blogging software “Cloud Paragraphs”. (Someone will now, I’m guessing.)

Coding with Clarity · An A List Apart Article

Good advice on writing code that is understandable to your fellow humans (and your future self).

plainJS - The Vanilla JavaScript Repository

Some more useful snippets of JavaScript. The functions and helpers are particularly handy if you’re weaning yourself off jQuery.

Essential Vanilla JavaScript Functions

The title is overkill, but these functions ported from PHP to JavaScript could be useful (especially for dealing with arrays).

Code clarity - Anthony Ricaud

Breaking down programming tasks into smaller chunks …and naming things.

I’ll take a piece of paper and write the function names I’m going to implement. Or I’ll do it directly in my code editor, with real functions or comments.

It allows you to focus on one problem at a time. When you’re writing those function names, you are thinking about what the code should be doing. When you’re implementing the functions, you are thinking about how the code should do it.

Callback Hell

At first when I was reading this JavaScript coding guide, I thought “Isn’t this exactly what promises address?” but that is then addressed further down:

Before looking at more advanced solutions, remember that callbacks are a fundamental part of JavaScript (since they are just functions) and you should learn how to read and write them before moving on to more advanced language features, since they all depend on an understanding of callbacks.

Fair enough. In any case, what you’ll find here is mainly good advice for writing modular code.

Making your JavaScript Pure · An A List Apart Article

I really like this piece by Jack. All the things he’s talking about—pure functions and referential transparency—are terms I was previously unfamiliar with …but the concepts smell familiar. It’s good to have terminology (and reasoning) to apply to the way I structure my JavaScript.
