Can enums be objects?

An enum is a data type that can be created by a Java programmer to represent a small collection of possible values. Technically, an enum is a class and its possible values are objects.

How do enums work JavaScript?

Enums are one of the few features TypeScript has which is not a type-level extension of JavaScript. Enums allow a developer to define a set of named constants. Using enums can make it easier to document intent, or create a set of distinct cases. TypeScript provides both numeric and string-based enums.

What is enumerator in JS?

The enumerator names are usually identifiers that behave as constants in the language. An enumerated type can be seen as a degenerate tagged union of unit type. A variable that has been declared as having an enumerated type can be assigned any of the enumerators as a value.

Is enum a data type in JavaScript?

In computer programming, an enumerated type (also called enumeration or enum [..]) is a data type consisting of a set of named values called elements, members or enumerators of the type.

Should enums be all caps C?

All-uppercase is a C language convention. A language that puts enum members in the global namespace. Very awkward, you have to come up with good names to avoid identifier collisions. Using all-uppercase helps with that, a short prefix is another way.
