In short the difference between the "devtool addon" and this library is the library operates in "push mode" where as the addon operates in "pull mode":

• push mode: you mark "huge" components with whyDidYouRender = true and proceed to work on your stuff. after some time suddenly you get notifications about the huge component being re-rendered.
• pull mode: you intentionally investigate performance issues and intentionally want to check why a specific component is re-rendered.
