26.3 Module Namespace Objects
A Module Namespace Object is a module namespace exotic object that provides runtime
property-based access to a module's exported bindings. There is no constructor function for
Module Namespace Objects. Instead, such an object is created for each module that is imported
by an ImportDeclaration that includes a NameSpaceImport.
In addition to the properties specified in 9.4.6 each Module Namespace Object has the
following own property:
26.3.1 @@toStringTag
The initial value of the @@toStringTag property is the String value "Module".
This property has the attributes { [[Writable]]: false, [[Enumerable]]: false, [[Configurable]]: false }.

A module namespace object is an exotic object that exposes the bindings exported from an
ECMAScript Module (See 15.2.3). There is a one-to-one correspondence between the String-keyed
own properties of a module namespace exotic object and the binding names exported by the
Module. The exported bindings include any bindings that are indirectly exported using export *
export items. Each String-valued own property key is the StringValue of the corresponding
exported binding name. These are the only String-keyed properties of a module namespace exotic
object. Each such property has the attributes { [[Writable]]: true, [[Enumerable]]: true,
[[Configurable]]: false }. Module namespace objects are not extensible.

Module Namespace Exotic Objects
A module namespace object is an exotic object that exposes the bindings exported from an
ECMAScript Module (See 15.2.3). There is a one-to-one correspondence between the String-keyed
own properties of a module namespace exotic object and the binding names exported by the
Module. The exported bindings include any bindings that are indirectly exported using export *
export items. Each String-valued own property key is the StringValue of the corresponding
exported binding name. These are the only String-keyed properties of a module namespace exotic
object. Each such property has the attributes { [[Writable]]: true, [[Enumerable]]: true,
[[Configurable]]: false }. Module namespace objects are not extensible.

26.3 Module Namespace Objects
A Module Namespace Object is a module namespace exotic object that provides runtime

Module Namespace Objects. Instead, such an object is created for each module that is imported
by an ImportDeclaration that includes a NameSpaceImport.
In addition to the properties specified in 9.4.6 each Module Namespace Object has the
following own property:

The initial value of the @@toStringTag property is the String value "Module".
This property has the attributes { [[Writable]]: false, [[Enumerable]]: false, [[Configurable]]: false }.

26.3 Module Namespace Objects
A Module Namespace Object is a module namespace exotic object that provides runtime
property-based access to a module's exported bindings. There is no constructor function for
Module Namespace Objects. Instead, such an object is created for each module that is imported
by an ImportDeclaration that includes a NameSpaceImport.
In addition to the properties specified in 9.4.6 each Module Namespace Object has the
following own property:
26.3.1 @@toStringTag
The initial value of the @@toStringTag property is the String value "Module".
This property has the attributes { [[Writable]]: false, [[Enumerable]]: false, [[Configurable]]: false }.
Module Namespace Exotic Objects
A module namespace object is an exotic object that exposes the bindings exported from an
ECMAScript Module (See 15.2.3). There is a one-to-one correspondence between the String-keyed
own properties of a module namespace exotic object and the binding names exported by the
Module. The exported bindings include any bindings that are indirectly exported using export *
export items. Each String-valued own property key is the StringValue of the corresponding
exported binding name. These are the only String-keyed properties of a module namespace exotic
object. Each such property has the attributes { [[Writable]]: true, [[Enumerable]]: true,
[[Configurable]]: false }. Module namespace objects are not extensible.

26.3 Module Namespace Objects
A Module Namespace Object is a module namespace exotic object that provides runtime
property-based access to a module's exported bindings. There is no constructor function for
Module Namespace Objects. Instead, such an object is created for each module that is imported
by an ImportDeclaration that includes a NameSpaceImport.
In addition to the properties specified in 9.4.6 each Module Namespace Object has the
following own property:
26.3.1 @@toStringTag
The initial value of the @@toStringTag property is the String value "Module".
This property has the attributes { [[Writable]]: false, [[Enumerable]]: false, [[Configurable]]: false }.
Module Namespace Exotic Objects
A module namespace object is an exotic object that exposes the bindings exported from an
ECMAScript Module (See 15.2.3). There is a one-to-one correspondence between the String-keyed
own properties of a module namespace exotic object and the binding names exported by the
Module. The exported bindings include any bindings that are indirectly exported using export *
export items. Each String-valued own property key is the StringValue of the corresponding
exported binding name. These are the only String-keyed properties of a module namespace exotic
object. Each such property has the attributes { [[Writable]]: true, [[Enumerable]]: true,
[[Configurable]]: false }. Module namespace objects are not extensible.

Module Namespace Exotic Objects
A module namespace object is an exotic object that exposes the bindings exported from an
ECMAScript Module (See 15.2.3). There is a one-to-one correspondence between the String-keyed
own properties of a module namespace exotic object and the binding names exported by the
Module. The exported bindings include any bindings that are indirectly exported using export *
export items. Each String-valued own property key is the StringValue of the corresponding
exported binding name. These are the only String-keyed properties of a module namespace exotic
object. Each such property has the attributes { [[Writable]]: true, [[Enumerable]]: true,
[[Configurable]]: false }. Module namespace objects are not extensible.

26.3 Module Namespace Objects
A Module Namespace Object is a module namespace exotic object that provides runtime
property-based access to a module's exported bindings. There is no constructor function for
Module Namespace Objects. Instead, such an object is created for each module that is imported
by an ImportDeclaration that includes a NameSpaceImport.
In addition to the properties specified in 9.4.6 each Module Namespace Object has the
following own property:
26.3.1 @@toStringTag
The initial value of the @@toStringTag property is the String value "Module".
This property has the attributes { [[Writable]]: false, [[Enumerable]]: false, [[Configurable]]: false }.
Module Namespace Exotic Objects
A module namespace object is an exotic object that exposes the bindings exported from an
ECMAScript Module (See 15.2.3). There is a one-to-one correspondence between the String-keyed
own properties of a module namespace exotic object and the binding names exported by the
Module. The exported bindings include any bindings that are indirectly exported using export *
export items. Each String-valued own property key is the StringValue of the corresponding
exported binding name. These are the only String-keyed properties of a module namespace exotic
object. Each such property has the attributes { [[Writable]]: true, [[Enumerable]]: true,
[[Configurable]]: false }. Module namespace objects are not extensible.

ECMAScript Module (See 15.2.3). There is a one-to-one correspondence between the String-keyed
own properties of a module namespace exotic object and the binding names exported by the
Module. The exported bindings include any bindings that are indirectly exported using export *
export items. Each String-valued own property key is the StringValue of the corresponding
exported binding name. These are the only String-keyed properties of a module namespace exotic
object. Each such property has the attributes { [[Writable]]: true, [[Enumerable]]: true,
[[Configurable]]: false }. Module namespace objects are not extensible.

26.3 Module Namespace Objects
A Module Namespace Object is a module namespace exotic object that provides runtime
property-based access to a module's exported bindings. There is no constructor function for
Module Namespace Objects. Instead, such an object is created for each module that is imported
by an ImportDeclaration that includes a NameSpaceImport.
In addition to the properties specified in 9.4.6 each Module Namespace Object has the
following own property:
26.3.1 @@toStringTag
The initial value of the @@toStringTag property is the String value "Module".
This property has the attributes { [[Writable]]: false, [[Enumerable]]: false, [[Configurable]]: false }.
