Fibonacci sequence using Generators

fibonacciGenerator.js

function* fibonacciGenerator() {
  const sequence = [0, 1];
  
  yield 0;
  yield 1;
  
  while (true) {
    let i = sequence.length;
    
    sequence[i] = sequence[i - 1] + sequence[i - 2];
    
    yield sequence[i];
  }
}

// Create the generator
const fibonacci = fibonacciGenerator();

// Use the new "fibonacci" generator
for (let i = 0; i <= 5; i++) {
  console.log(fibonacci.next());
}
// Result:
// { value: 0, done: false }
// { value: 1, done: false }
// { value: 1, done: false }
// { value: 2, done: false }
// { value: 3, done: false }
// { value: 5, done: false }
