A Book Nerd’s Guide to JavaScript @angustweets

Practical, Useful, Mind Numbingly Boring Nonsensical Work of Genius
What can Literature teach us about Programming?
Great literature is the creation of open minds As programmers
our focus can be very narrow
We’re encouraged to follow only one style…
Actual excerpts from: Google Style Guide AirBnb Style Guide JavaScript

We’re left with only one way to get from A

Literature is about embracing the entire language

"There are indeed many ways to do the same thing
in JS. That's one of the beauties of the language" - Peter van der Zee (@kuvos)

(at least until the JavaScript Police get here)

Perhaps most importantly…
…Open Minds keep JavaScript fun.
This one just follows The Good Parts These two learn
by experiment
As programmers we’re not encouraged to experiment
Yet experiment is what keeps JavaScript alive
“You need a lot of bad code to write good
code” - Substack (dotJS 2014)
‣ if(!!x) ‣ fn && fn() ‣ immediately invoked functions
‣ module pattern ‣ promises
None
I decided to take experiment to the next level…

Hemingway developed the Iceberg Theory
Here is Hemingway’s Iceberg Theory applied to JavaScript…

So what did we learn?
Playing is Learning
Self-taught programmers are often the best programmers because they get
to make mistakes
Experiment, Play, Have Fun and Keep an Open Mind.
