PhantomCodeAI generates complete solutions and debugging hints that you can use while explaining your approach, so you stay calm and in control.
Call Function with Custom Context
Add callPolyfill to all functions. Calling fn.callPolyfill(obj, ...args) must invoke fn with obj as its this context and the remaining arguments passed to fn, and return its result. Implement this without the built-in Function.call method.
