That is why _.find() and _.findWhere() are different

During my work on web project for US client, I faced with interesting issue, which at the first look seemed to be related to D3.js/C3.js donut charts, but after deep debugging, I discovered it’s because of nature of Underscore.JS 1.6.0 library/code. I would say, it’s bright example of the fact how important to know main purpose of dedicated API/tool, and implement custom codebase for the future to be working also correct.
