Hi, reader. I wrote this in 2013 and it's now more than five years old. So it may be very out of date; the world, and I, have changed a lot since I wrote it! I'm keeping this up for historical archive purposes, but the me of today may 100% disagree with what I said then. I rarely edit posts after publishing them, but if I do, I usually leave a note in italics to mark the edit and the reason. If this post is particularly offensive or breaches someone's privacy, please contact me.
This week I started remembering JavaScript (two years ago I picked up a little bit). A few fun things:
Math.random
, make and use arrays and Object
s, display things in a webpage, write for
loops, get input from the user using prompt()
, and put semicolons everywhere.
for
loop keeps happening until the step when the run condition is no longer satisfied, so it's sort of more like a while
loop? Anyway this tripped me up and gave me an off-by-one error until I grokked it.
print()
and show()
that give me stark errors in Node.
