I totally agree, and my use of JScript(er) has been the first in the last few years, the last was when I was teaching a bunch of school kids about Web technologies. I don&#x27;t intend to use it again and only arose out of laziness than ignorance.<p>Are there any other such bad practices in the JS dev world? I&#x27;ve only just considered moving onto Node as I&#x27;ve grown disillusioned with Rails and the concept of using a single language across the entire app &amp; mobile (React Native, etc) sounds enticing.
