I like to think of writing code similar to designing puzzles.
The more simple the code, the easier to dissect each individual element and
know the code with exact precision.
However, I have a fondness for diving deep into code I don’t understand.
One of my favorite things to do is to find a method on ruby-docs that I know
nothing about, and pick it apart piece by piece.
Originally, I used mass amounts of puts and tabbing back and forth between
my editor and irb. During my first day at the IronYard my Instructor James
introduced me to Pry.
Let me say, pry is a dream.
Pry is pretty sweet because I’m able to use pry in place of irb.
It also uses a colorized
text to help me instantly recognize what the type the presented code is.
For me, the most powerful feature of pry is binding.pry
.
When I’m wanting to find out what a particular piece of code is doing
at a specific point in time, I drop binding.pry
at that specific
line. Then when I run the code, pry automatically opens and I’m given the ability
to check specific states of code, even during complicated loops.
In addition, I like to use the pry-byebug gem to be able to go line by line,
continuously being able to check code and debug/figure out whats going on.
As a Junior Dev I find these practices to be crucial.
There are plenty of times I have no idea what I’m doing, and by calmly
dissecting the code, I can pull myself through even the hardest bits of code.
