Changelist

This pull request contains my solution for the Sprint 1 - Refactor exercise in the Module Data-Groups.

Refactor

Refactored the implementation of the includes function in:

• Sprint-1/refactor/includes.js

Changes made:

• Replaced the indexed for loop with a for...of loop
• Simplified the implementation while keeping the same behaviour
• Ensured the function still checks whether the target value exists in the array

The existing test cases in:

• Sprint-1/refactor/includes.test.js

were used to confirm that the refactored implementation still works correctly.

---

Testing

All tests were run locally using:

cd Sprint-1
npm test -- refactor

All tests passed successfully.
