Enum boa::syntax::ast::node::PropertyDefinition

pub enum PropertyDefinition {
    IdentifierReference(Box<str>),
    Property(Box<str>, Node),
    MethodDefinition(MethodDefinitionKind, Box<str>, FunctionExpr),
    SpreadObject(Node),
}

A JavaScript property is a characteristic of an object, often describing attributes associated with a data structure.

A property has a name (a string) and a value (primitive, method, or object reference). Note that when we say that "a property holds an object", that is shorthand for "a property holds an object reference". This distinction matters because the original referenced object remains unchanged when you change the property's value.

Variants

IdentifierReference(Box<str>)

Puts a variable into an object.

• ECMAScript reference
• MDN documentation

Property(Box<str>, Node)

Binds a property name to a JavaScript value.

More information:

• ECMAScript reference
• MDN documentation

MethodDefinition(MethodDefinitionKind, Box<str>, FunctionExpr)

A property of an object can also refer to a function or a getter or setter method.

• ECMAScript reference
• MDN documentation

SpreadObject(Node)

The Rest/Spread Properties for ECMAScript proposal (stage 4) adds spread properties to object literals. It copies own enumerable properties from a provided object onto a new object.

Shallow-cloning (excluding prototype) or merging objects is now possible using a shorter syntax than Object.assign().
