Configuration file is a simple JSON file that specifies which JSHint options to turn on or off. Inline configuration /* jshint undef: true, unused: true */ /* global MY_GLOBAL */ Directives jshint /* jshint strict: true */
Using Google's Closure to Compile and Verify your JavaScript
7, Mar 2013 A large application is nearly guaranteed to come with an equally large amount of JavaScript attached to it. During development it makes sense to divide the JavaScript of the application into multiple sensibly named files both to make finding specific functionality in the code base easier, and to keep the file length to a reasonable size for readability/comprehension purposes. More importantly though, this allows you to build modular, reusable components by separating functionality and sharing common methods within the application. However, when it comes time to move your site to the production environment, this development processes' inefficiencies become noticeable in slow loading pages. One way that these problems can be mitigated by combining all the multiple JavaScript files into a single compiled file. Introducing Google Closure The Google Closure Compiler is a tool designed to solve these problems. How to Get it Sounds great right? That's all there is to it! How to Use it
