Variants

This(This)

The ECMAScript this keyword refers to the object it belongs to.

Implementations

impl Expression

pub const fn is_anonymous_function_definition(&self) -> bool

Returns if the expression is a function definition without a name.

More information:

• ECMAScript reference

pub fn set_anonymous_function_definition_name(&mut self, name: &Identifier)

Sets the name of an anonymous function definition.

This is used to set the name of a function expression when it is assigned to a variable. If the function already has a name, this does nothing.

pub const fn flatten(&self) -> &Expression

Returns the expression without any outer parenthesized expressions.
