The Pug Template engine compiles a subset of JavaScript (ES2015) to Go templates. Nevertheless, extensive usage of JavaScript is not advised. Please note that these function have to use reflection and it's up to the implementation to properly reflect the functionality and handle different inputs correctly. However, it is possible to recreate such functionalities in a third-party module via Flamingo's template functions.įor example pug_template itself has a substitute for the JavaScript Math library with the min, max and ceil functions. Only snippets of JavaScript code can be run. This time let's work in main-layout.pug just to show that we can use dynamic data in our layout files. Looping Now let's check out how we can iterate over our array of user names. The ideal Body Condition Score for a Pug should be 3/5 or 5/9.

Pug gives us a nice clean way to perform conditional rendering based on passed in data. The Pug is a breed of dog originally from China, with physically distinctive features of.
