Rails Best Practices

Put scripts at the bottom

Do you experience that your website renders slow due to loading a lot of javascripts, especially loading some third-party javascripts? Move script tags to the bottom of body can speed up the render of your website.

Not use time_ago_in_words

It's very common for a rails developer to use time_ago_in_words to display time like "5 minutes ago", but it's too expensive to calculate the time in server side, you should utilize client cpu to calculate the time ago.
