Give variables and functions descriptive names, such as firstName,
homeworkScore, or getAverageTemperature.
Avoid single-letter variable names like xor c,
except for loop variables like i.
Letter-Casing and Special Characters
Name variables and functions with camel-casing likeThis, name classes
with Pascal casing LikeThis, and name unchanging "constant" variables
in all-uppercase LIKE_THIS. Variables and functions should never
include "-" or start with numbers in JavaScript.
