JavaScript | functions are named with reserved keywords

Question

I'm watching a video on Revealing Module Pattern and the instructor named some of his functions with "add" and "get" and I'm super confused because I thought those words are reserved(add is used for Sets and get is used to return elements from Map objects). So how come this allowed?

Answer 1

add and get aren't reserved in JavaScript, but get is reserved in C#, Java, C++ etc.. In JavaScript It's allowed to define a function like "get" or "add". But you're right, It's dangerous to use names like these.
