title: Ext js coding standards/ best practice
body: <p>Can anyone share ext js coding standards? Is it worth enough to have two versions of js files - one during development and another compressed version for production environment?</p>
  
  <p>Also can any one suggest on the number of JS files we can have. I read some where that js files gets downloaded serially and hence avoid adding new files just for the sake of readability. Rather to have the contents in minimal number of files. Is this true ?</p>
