Question

what is JavaScript and camel case?​

Answer 1

Answer:

Historically, programmers have used three ways of joining multiple words into one variable name:

Hyphens:

first-name, last-name, master-card, inter-city.

Underscore:

first_name, last_name, master_card, inter_city.

Camel Case:

FirstName, LastName, MasterCard, InterCity.

In programming languages, especially in JavaScript, camel case often starts with a lowercase letter:

firstName, lastName, masterCard, interCity.
