We are currently studying the phenomenon where developers replace self-implemented code with an equivalent external method, as well as the phenomenon where developers switch from using an external method to implementing an equivalent one themselves. We invite you to participate this survey, which takes you about 5-10 minutes. The results can help us improve the current code recommendation systems. Please note that all answers provided in the context of this survey will be treated anonymously.
