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

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:

$ npm install -g eslint

And just typing:

$ 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.

Are you a C# developer curious about the awesome things happening in the JavaScript world? Would you like to be a part of it? Build super rich web applications, mobile apps, backend services or even robots? Does JavaScript frustrate you?

Then this is the book for you! With this book you’ll get a great introduction to JavaScript and ES6 from a C# perspective. You’ll learn the most common pitfalls and weird behaviors and end up enjoying writing JavaScript just as much as you do C#.

And it has wizards!

This is the first book of the JavaScript-mancy series. Within its mysterious pages you’ll find:

  • A great introduction to the JavaScript language full of fantasy inspired examples and exercises
  • A detailed look at the new and awesome ES6 features in a historical context, highlighting why they exist and which problems they’re trying to solve
  • A lot of references to C# that will make it super easy for C# developers to wrap their heads around JavaScript and its quirks. (This also extends to developers familiar with strongly typed languages)
  • A breathtaking story of EPIC proportions and awkward sense of humor

For you, dear reader, I have created a time limited coupon so that you can get an awesome 30% discount on the book. Enjoy!! Hope that you love it! There’s a lot of love in those pages.

P.S. Funny thing is that, even if you are not a C# developer, this is an awesome book to get started with JavaScript. If you are into the fantasy theme, take a look at the sample book and see if it is something that you find appealing.
