Package description

What is @babel/plugin-proposal-private-methods?

The @babel/plugin-proposal-private-methods package is a Babel plugin that allows developers to use the private methods and accessors proposal in JavaScript classes. This proposal is part of the ECMAScript (ES) standardization process and introduces a way to define private methods and getter/setter functions in a class, which are only accessible within the class itself.

What are @babel/plugin-proposal-private-methods's main functionalities?

Private Methods

This feature allows the definition of methods in a class that are not accessible from outside the class. The hash (#) prefix indicates that the method is private.

class MyClass {
  #privateMethod() {
    return 'Hello from private method';
  }

  publicMethod() {
    return this.#privateMethod();
  }
}

Private Accessors

This feature allows the definition of private getter and setter functions in a class, which can be used to control access to private fields.

class MyClass {
  #privateField = 'private value';

  get #privateAccessor() {
    return this.#privateField;
  }

  set #privateAccessor(newValue) {
    this.#privateField = newValue;
  }

  publicMethod() {
    return this.#privateAccessor;
  }
}
