Reading the docs of an unnamed CDP. It’s a very impressive app whose tag manager piece easily outclasses GTM (I consider GTM the spawn of a minor demon). Then I come across this:
Huh? Typing the 9 ASCII letters in
abcdefghi a hundred times doesn’t add 900 characters — 900 bytes is how we actually measure size on the wire, btw — because JS files are highly compressible.
The difference between a single
a × 100 and
abcdefghi × 100, after standard gzip/deflate compression, is meaningless: a 28 byte difference in an otherwise random 1KB file.
Nobody cares about that.
Just say you think a one-letter variable is easier to remember! Otherwise you’re spreading misinformation that leads newbie developers to use variable names like
b. So frustrating.
