Variable names are case sensitive, so
ANSWER
is different to
Answer
and
answer
.
When using multiple words for variable names there are two conventions
that can be used. Camel case starts with a lowercase letter and then each
new word is capitalized:
firstNameAndLastName
Underscore separates each new word with an underscore:
first_name_and_last_name
JavaScript's built-in functions use the camel-case notation, but you can
choose to use one or the other or a combination of the two when naming
variables. What's important for a ninja is to
be consistent
