Class ClassDefinition

An ECMAScript 2015 or TypeScript class definition, that is, either a class declaration statement or a class expression.

Examples:

class Rectangle extends Shape {   // class declaration statement
  constructor(width, height) {
    this.width = width;
    this.height = height;
  }

  area() { return this.width * this.height; }
}

let C =
class {                           // class expression
  constructor() { this.x = 0; }

  bump() { return this.x++; }
};
