Extending generators with a toArray method.

Generators miss a toArray method.

Here is an implementation:

Object.defineProperty(
 Object.getPrototypeOf(function* () {}).prototype,
 "toArray",
 {
   value: function () { return Array.from(this) }
 }
);

Here a use case :

Object.defineProperty(
 Object.getPrototypeOf(function* () {}).prototype,
 "toArray",
 {
   value: function () { return Array.from(this) }
 }
);

function* range (start , end ) {
  while (start <= end) {
    yield start++
  }
}

let r10to20 = range(10, 20).toArray()

console.log(r10to20)  // [ 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20 ]
