5 Expressions

Expressions in Haxe define what a program does. Most expressions are found in the body of a method, where they are combined to express what that method should do. This section explains the different kinds of expressions. Some definitions help here:

Define: Name

A general name may refer to
a type,
a local variable,
a local function or
a field.

Define: Identifier

Haxe identifiers start with an underscore _, a dollar $, a lower-case character a-z or an upper-case character A-Z. After that, any combination and number of _, A-Z, a-z and 0-9 may follow.

Further limitations follow from the usage context, which are checked upon typing:
Type names must start with an upper-case letter A-Z or an underscore _.
Leading dollars are not allowed for any kind of name (dollar-names are mostly used for macro reification).

since Haxe 3.3.0

Haxe reserves the identifier prefix _hx_ for internal use. This is not enforced by the parser or typer.
