Janet supports several varieties of types that can be used as labels for things in
|
||||
your program. The most useful type for this purpose is the keyword type. A keyword
|

begins with a semicolon, and then contains 0 or more alphanumeric or a few other common
|

characters. For example, `:hello`, `:my-name`, `:=`, and `:ABC123_-*&^%$` are all keywords.

characters. For example, `:hello`, `:my-name`, `::`, and `:ABC123_-*&^%$` are all keywords.
|

Keywords are actually just special cases of symbols, which are similar but don't start with
|
||||
a semicolon. The difference between symbols and keywords is that keywords evaluate to themselves, while
|
||||
symbols evaluate to whatever they are bound to. To have a symbol evaluate to itself, it must be

Bindings created with def have lexical scoping. Also, bindings created with def are immutable; they

cannot be changed after definition. For mutable bindings, like variables in other programming
