es6-class

esnext61Apache 20.9.5

ES6 classes compiled to ES5.

readme (leia-me)

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 the equivalent with Person as a function. See the esnext demo page for more on the behavior and generated JavaScript.

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