Introduction

Here is some collected wisdom from the webOS development community.

Coding

• Use a tool like JSLint or JSure to check your code for typos and other potential coding mistakes
• Pick a coding standard that you are comfortable with and stick with it
• Learn Test Driven Development: Mojo™ Test Framework

Debugging

• To help with debugging, use Mojo.Log.info("%j", object) to log out the contents of an object. This is invaluable to use when getting responses from Mojo service requests to see what actually came back.
• When code isn't working write, wrap it in try/catch blocks. Not all errors will be logged automatically and sometimes errors occur in places you don't expect.
