Lifespan of a Feature

Development Staging Production Testing Feature Rollout Default Activation Full Integration

Implementation Conclusion

10. Internationalization

Conclusion

A. JavaScript Style Guide

Example Tests QUnit Primer Code Quality Best Practices Quick Reference

Indentation: Be Consistent Use Semicolons Bracket Placement: Right Side Avoid Name Collisions Always Use var Use One var Statement per Function Avoid Constant Abuse Use Functional Iterators When Possible Be Careful with if Statements Avoid Side Effects Don’t Use switch Don’t Use eval()
