@vsemozhetbyt Thanks truly for the formatting advice!
So there's a couple things wrong with it as I was doing the tutorial:
- The section is basically turning global vars into local vars by turning into functions (as I understood to eliminate any side-effects), the author did so except for the anonymous function "nolanMovies" which defeats the purpose of the exercise - which confused like a beginner like me
- It's missing a return statement
from thejsway.
@Jemaz I suppose both using the global variable and omitting the return
are intended to show how a not pure function operates. It is a bit dizzying from the final point of view, but maybe this is the very sense of it)
from thejsway.
What was a bit more confusing for me: why the final byNolan()
was not refactoring into the more generic byDirector(director)
. But this can also be intended to make the transition from the old code to the new one more smooth.
from thejsway.
Excuse me for the bad formatting, still a newb to this.
from thejsway.
@Jemaz It seems this function uses the global variable that is declared below in that code fragment:
//...
const nolanMovieList = [];
console.log(titles());
// ...
from thejsway.
@Jemaz About formatting, you can read here:
https://help.github.com/articles/creating-and-highlighting-code-blocks/
Just use js
or javascript
label instead of ruby
from the example in that help chapter)
from thejsway.
Thanks for your feedback. This chapter gave me a lot of headaches and is probably still too confusing. I leave this issue open in case someone else can provide good advice for improving it.
