Create getArrayMaxValue function

[Godelvatai]

Created getArrayMaxValue function and setup test cases for the new fucntion

[jbb-codes]

The logic for finding the max value looks correct overall, but there is a bug blocking all tests from passing.

Bug — src/utils/getArrayMaxValue.js, line 13

isArray is a static method on the Array constructor, not an instance method on arrays. This throws a TypeError on every call, including valid inputs.

// Current (broken)
if (!arr.isArray()) {

// Fix
if (!Array.isArray(arr)) {

Minor Issues

• Both files are missing a newline at the end of the file. Most editors and linters expect one.

Suggested Improvements

• Handle empty arrays — if [] is passed, Math.max() returns -Infinity. Consider adding a check after the Array.isArray validation and a corresponding unit test.
• Handle arrays with no valid numbers — if every element is a non-number (e.g., ['a', 'b', 'c']), the filter strips everything out and Math.max() again returns -Infinity. Consider validating the filtered result before calling Math.max and adding a unit test for this case.

What's Working

• The Math.max with filter approach correctly handles non-number values and zeros.
• Test coverage is solid — all four cases are meaningful.

Please fix the Array.isArray call — once corrected, all 4 tests should pass. Requesting changes until then.
