In this lab, you will create a generator function that returns a generator object which yields the Fibonacci sequence. The Fibonacci sequence is defined by the relation Xn = Xn-1 + Xn-2. The first few numbers of the series are 0, 1, 1, 2, 3, 5, 8, 13.

Lab Requirements

  • Use ESM import/export everywhere.
  • Write a bug-free code.
  • Pass all the challenges provided in the lab.

Examples

Example 1:

Input: callCount = 5
Output: [0, 1, 1, 2, 3]
Explanation:
const gen = fibGenerator();
gen.next().value; // 0
gen.next().value; // 1
gen.next().value; // 1
gen.next().value; // 2
gen.next().value; // 3

Example 2:

Input: callCount = 0
Output: []
Explanation: gen.next() is never called so nothing is outputted

Example 3:

Input: callCount = 10
Output: [0, 1, 1, 2, 3, 5, 8, 13, 21, 34]
Explanation:
const gen = fibGenerator();
gen.next().value; // 0
gen.next().value; // 1
gen.next().value; // 1
gen.next().value; // 2
gen.next().value; // 3
gen.next().value; // 5
gen.next().value; // 8
gen.next().value; // 13
gen.next().value; // 21
gen.next().value; // 34

Constraints:

  • 0 <= callCount <= 50
