ES6 classes compiled to ES5.

es6-class

Compiles JavaScript written using ES6 classes to use ES5-compatible function syntax. For example, this:

class Person {
  constructor(firstName, lastName) {
    this.firstName = firstName;
    this.lastName = lastName;
  }

  get name() {
    return this.firstName + ' ' + this.lastName;
  }

  toString() {
    return this.name;
  }
}

compiles to this:

var Person = function() {
  function Person(firstName, lastName) {
    this.firstName = firstName;
    this.lastName = lastName;
  }

  Object.defineProperty(Person.prototype, "name", {
    get: function() {
      return this.firstName + ' ' + this.lastName;
    },

    enumerable: false
  });

  Object.defineProperty(Person.prototype, "toString", {
    value: function() {
      return this.name;
    },

    enumerable: false
  });

  return Person;
}();```

For more information about the proposed syntax, see the [wiki page on
