Enum ForLoopInitializer 

pub enum ForLoopInitializer {
    Expression(Expression),
    Var(VarDeclaration),
    Lexical(ForLoopInitializerLexical),
}

A ForLoop initializer, as defined by the spec.

A ForLoop initializer differs a lot from an IterableLoopInitializer, since it can contain any arbitrary expression instead of only accessors and patterns. Additionally, it can also contain many variable declarations instead of only one.

Variants

Expression(Expression)

An expression initializer.

Var(VarDeclaration)

A var declaration initializer.

Lexical(ForLoopInitializerLexical)

A lexical declaration initializer.
