Chapter 1: Introducing ECMAScript 6

Activity 1 – Implementing Generators

You have been tasked with building a simple app that generates numbers in the Fibonacci sequence upon request. The app generates the next number in the sequence for each request and resets the sequence it is given an input. Use a generator to generate the Fibonacci sequence. If a value is passed into the generator, reset the sequence. You may start the Fibonacci sequence at n=1 for simplicity.

To highlight how the generators can be used to build iterative datasets, follow these steps:

1. Look up the Fibonacci sequence and understand how the next value is calculated.
2. Create a generator for the Fibonacci sequence.
3. Inside the generator, set up the default values for current and next (0, 1) using variables n2 and n1.
4. Create an infinite while loop.
5. Inside the while loop, use the yield keyword to provide the current value in the sequence and save the return...
