I'm someone who likes working close to the metal, but I like
|
|
the way they explained using encapsulation to design your code
|
|
|
|
I've often found myself wondering how to organize code,
|
|
but this concept of, write code until you feel that peice
|
|
is done, wrap it into a function, and then move onto
|
|
the next step, somewhat made it click a bit better for me.
|
|
|
|
Having used Lisp, I've loved the lots of small functions
|
|
concept, but I suppose I always had trouble with design.
|
|
Somehow, thinking about it this way, works for me.
|
|
* 1 not clear
|
|
The difference between null and undefined.
