Code Review: Utility Function

MediumPython

Problem

Walk me through a code review of this utility function: const isNotNil = (v) => !!v;

Explain whether the implementation matches the function name, identify important JavaScript edge cases, and provide a corrected implementation. For grading, implement the intended predicate in Python: return True for every value except None.

Signature: def is_not_nil(value):

Input/output: Accept any JSON-compatible value and return a boolean.

Constraints

  • The input is any JSON-compatible value.
  • Return false only when the input is None.
  • Do not use general truthiness to determine whether a value is nil.

Function Signature

def is_not_nil(value):
