This PR covers work in the Test-First Development section of the sprint project:

Test-First Approach:

Wrote Jest tests before implementing the functions, practicing the test-driven development (TDD) process.

Jest Tests: Created and completed test files for:

• count.test.js
• repeat-str.test.js
• get-ordinal-number.test.js

Each test file follows the provided acceptance criteria and uses Jest’s syntax for clarity.

Functions were then implemented to make all tests pass.

All tests run successfully with the VS Code Test Runner or by using npm test.

This PR branch is not clean; it contains changes unrelated to "Practice TDD" exercise.
Can you revert the changes made in Sprint-2 and Sprint-3/1-implement-and-rewrite-tests folders?

Note: Your other Sprint-3 PR branch, #832, is also not clean.

If you have difficulty reverting the changes, please seek assistance from a volunteer in an in-person workshop. Alternatively, you can create new branches (make sure they are created from your main branch), transfer your Sprint-3 exercise files to the new branches, and submit new PRs (and then close the old Sprint-3 PRs).
