Conclusions

• Choose a library to suit your needs: don't adjust your needs to fit the way a library works.
• If you use a library, understand how it works so that you aren't clueless when something goes wrong.
• Remember the end user: a library might make your life easier, but at what cost? (filesize, browser compatibility, etc.).
