-> **Note:** Private features have the restriction that all property names declared in the same class must be unique. All other public properties do not have this restriction — you can have multiple public properties with the same name, and the last one overwrites the others. This is the same behavior as in [object initializers](/en-US/docs/Web/JavaScript/Reference/Operators/Object_initializer#duplicate_property_names).

-Class fields are similar to object properties, not variables, so we don't use keywords such as `const` to declare them. In JavaScript, [private features](#private_class_features_2) use a special identifier syntax, so modifier keywords like `public` and `private` should not be used either.

 As seen above, the fields can be declared with or without a default value. Fields without default values default to `undefined`. By declaring fields up-front, class definitions become more self-documenting, and the fields are always present, which help with optimizations.
