import React from "react";

export const createGenericContext = <T extends unknown>() => {
  // Create a context with a generic parameter or undefined
  const genericContext = React.createContext<T | undefined>(undefined);

  // Check if the value provided to the context is defined or throw an error
  const useGenericContext = () => {
    const contextIsDefined = React.useContext(genericContext);
    if (!contextIsDefined) {
      throw new Error("useGenericContext must be used within a Provider");
    }
    return contextIsDefined;

};
