• originalImplementation is an object that contains functions that have the original implementation for this recipe. They can be used in your functions as a way to use the SuperTokens' default behaviour.
• In the above code snippet, we override the signInAndUp function of the ThirdParty recipe and signUp of the EmailPassword recipe. This means that when the user clicks the sign up button in the UI, your function will be called with the relevant input object.
