Package description
The @babel/plugin-proposal-private-property-in-object package is a Babel plugin that allows developers to use the `#private in object` syntax to check for the existence of a private property within an object. This is part of a proposal for ECMAScript and is not yet part of the official language specification. The plugin transforms this syntax into a form that can be understood by current JavaScript engines.
Private property existence checks
This feature allows developers to check if a private field exists in an instance of a class. The code sample demonstrates how to define a private field and then check for its existence using the `in` operator.
class MyClass {
#myPrivateField;
hasPrivateField(obj) {
return #myPrivateField in obj;
}
}This package allows developers to use the public and private class fields syntax. It is similar to @babel/plugin-proposal-private-property-in-object in that it deals with class field declarations, but it does not specifically provide the functionality to check for private property existence within an object.
This package enables the use of private methods and accessors in classes. Similar to @babel/plugin-proposal-private-property-in-object, it deals with private aspects of classes, but focuses on methods and accessors rather than properties.
