Barbaric Tip of the Week: Learn Functional Programming in JavaScript With Professor Frisby

| Comments

Barbaric Tip of the Week is a weekly series whose main purpose is to share tiny bits of knowledge that I find specially useful and interesting.

20th of December… 2016 is drawing to an end… If you are like me you’re already freaking out about all the things that you wanted to do but didn’t. Was, by any change, learning more about functional programming one of those new year resolutions you had last year? Or something you just became more interested in throughout 2016 but you never got around to? Then today is your lucky day because I have something for you that will let you finish 2016 strong or start 2017 with great footing: The marvellous Professor Frisby Introduces Composable Functional JavaScript course.

Brian Lonsdorf brings his Professor Frisby’s Mostly Adequate Guide to Functional Programming to life in these series of great videos on functional programming available as a free course on egghead.io.

Learn JavaScript FP with Professor Frisby!

The video course is only an hour a half long with a very pragmatic approach driven by code samples. I recommend following along with your own session of jsbin or jsFiddle and tinker with the examples yourself. Hope that you enjoy it! Have an awesome week ahead!

Behold the New JavaScriptmancy.com! Your #1 Destination to Learn Javascript! Necromancer Style!!

Ever since I started writing the javascriptmancy books I envisioned a beautiful place in the interwebs where I could place not only the book but a host of interactive resources to learn JavaScript. Behold! JavaScript-mancy.com!!!!

The JavaScriptmancy.com website

At this point you can find all the books that I have written thus far, the value proposition, the backstory, a short bio and most interestingly an interactive sample of the books themselves. Yey!

It doesn’t fulfill my complete vision yet but it is a teeny tiny step in the right direction. Hope you like it!

How to Create a Simple Chrome Extension to Hide Your Follower Number on Twitter

Twitter followers.

I know I shouldn’t care, I know I shouldn’t feel bad when someone unfollows me nor overly proud or happy when people follow me but I kind of do.

I suppose it is just human nature and trying to fill that basic need to feel valued and validated… but I will have none of it! Twitter, I shall be driven by intrinsic motivation and not by artificial and arbitrary external rewards!! You shall not control me! (tantrum xD)

Since it seems that I cannot do it by sheer willpower (I have tried), I came up with a better idea. What about removing the source of my troubles completely? Out of sight, out of mind right?

And that’s how this chrome extension and this very blog post came about. Are you curious about how to write a chrome extension to run arbitrary code on any given website? Then follow along!

Barbaric Tip of the Week: Configure Eslint Super Quickly With Eslint Init

| Comments

Barbaric Tip of the Week is a weekly series whose main purpose is to share tiny bits of knowledge that I find specially useful and interesting.

eslint is a JavaScript linter, a static analysis tool, that helps you find errors in your JavaScript code before executing it and conform to a predefined set of styles for better uniformity. Since JavaScript is a dynamic language this is very useful as it behaves like a lightweight compiler and warns you of common errors as soon as they’re introduced.

I started using eslint because it was the first JavaScript linter that brought a solid support for ES6. It had a small problem though, it was not completely straightforward to setup and configure. I remember the two first times I used eslint I had to scourge the web to try to understand how to get a sane default configuration for my projects. But fortunately that’s not longer the case!

Now you can get started with eslint by installing it via npm:

1
$ npm install -g eslint

And just typing:

1
$ eslint --init

Get started with eslint

You can get your code analyzed and be offered some suggestions, or select popular style guides (like Google’s) or just answer questions regarding your preferences:

Get started with eslint

Awesome right? That’s a nice developer experience right here. So now go forth and lint.
