Describe your change:

  • Fix a bug or typo in an existing algorithm

This PR improves the mean function by:

  • Adding input validation:
    • Throws TypeError if input is not an array or contains non-number elements
    • Throws Error if array is empty
  • Adding a comprehensive test suite using Vitest, which includes:
    • Empty arrays
    • Invalid elements like null, true, 'string'
    • Floating-point numbers, negative values, large values
    • Mixed integer and float arrays

The function now adheres more strictly to the expected behavior and is more robust against invalid input.

  • This PR only changes one algorithm file. To ease review, please open separate PRs for separate algorithms.
  • All new JavaScript files are placed inside an existing directory.
  • All filenames use the UpperCamelCase (PascalCase) style.
  • All new algorithms have a URL in their comments that points to Wikipedia or another similar explanation.
