Frontend Task Checklist

IMPORTANT NOTICE 🚨:

The Ivy Docs represent the ground truth for the task descriptions and this checklist should only be used as a supplementary item to aid with the review process.

LEGEND 🗺:

• ❌ : Check item is not completed.
• ✅ : Check item is ready for review.
• 🆘 : Stuck/Doubting implementation (PR author should add comments explaining why).
• ⏩ : Check is not applicable to function (skip).
• 🆗 : Check item is implemented and does not require any edits.

CHECKS 📑:

1. • ✅: The function/method definition is not missing any of the original arguments.
2. • ⏩: In case the function/method to be implemented is an alias of an existing function/method:
     1. • ⏩: It is being declared as such by setting fun1 = fun2, rather than being re-implemented from scratch.
     2. • ⏩: The alias is added to the existing function/method's test in the aliases parameter of handle_frontend_test/handle_frontend_method.
3. • ✅: The naming of the function/method and its arguments exactly matches the original.
4. • ✅: No defined argument is being ignored in the function/method's implementation.
5. • ⏩: In special cases where an argument's implementation should be pending due to an incomplete superset of an ivy function:
     1. • ⏩: A descriptive comment has been left under the Implement superset behavior ToDo list in Implement superset behavior #6406.
     2. • ⏩: A ToDo comment has been added prompting to pass the frontend argument to the ivy function whose behavior is to be extended.
6. • ✅: In case a frontend function is being added:
     1. • ✅: It is a composition of ivy functions.
     2. • ⏩: In case the needed composition is long (using numerous ivy functions), a Missing Function Suggestion issue has been opened to suggest a new ivy function should be added to shorten the frontend implementation.
     3. • ✅: @to_ivy_arrays_and_back has been added to the function.
7. • ⏩: In case a frontend method is being added:
     1. • ⏩: It is composed of existing frontend functions or methods.
     2. • ⏩: If a required frontend function has not yet been added, the method may be implemented as a composition of ivy functions, making sure that:
          • ⏩: @to_ivy_arrays_and_back has been added to the method.
          • ⏩: A ToDo comment has been made prompting to remove the decorator and update the implementation as soon as the missing function has been added.
8. • ✅: The function/method's test has been added (except in the alias case mentioned in <2>):
     1. • ✅: All supported arguments are being generated in handle_frontend_test/handle_frontend_method and passed to test_frontend_function/test_frontend_method.
     2. • ✅: The argument generation covers all possible supported values. Array sizes, dimensions, and axes adhere to the full supported set of the original function/method.
     3. • ❌: The available_dtypes parameter passed to the helper generating the function/method's input array is set to helpers.get_dtypes("valid"). If there are unsupported dtypes that cause the test to fail, they should be handled by adding @with_supported_dtypes/@with_unsupported_dtype to the function/method.
9. • ✅: The PR is not introducing any test failures.
     1. • ✅: The lint checks are passing.
     2. • ✅: The implemented test is passing for all backends.
10. • ✅: The PR closes a Sub Task issue linked to one of the open frontend ToDo lists.
11. • ✅: The function/method and its test have been added to the correct .py files corresponding to the addressed ToDo list.
12. • ✅: The PR only contains changes relevant to the addressed subtask.

@arshPratap
Hiya, thank you for the cotributions, may I ask you to do a quick fix relating to 8) of the checklist? Using "valid" instead of "float" will just make the test more robust.

After that, I can get it merged!
