Transitioning to strict mode

[David Bruant]

Hi,

I'd like to share a piece of documentation I've recently written [1]. 
It's a guide to help developers understand how they can transition to 
strict mode and what they should be aware of while making this transition.
Differences between strict and non-strict are divided into 3 categories: 
syntax errors, runtime errors, semantic changes.
Each category requires a different amount of work and attention from 
developers.

I'm looking forward to any recommendation you'd have to improve this 
guide, specifically about the runtime errors where I said something 
about "100% coverage test suite" and I'm not entirely sure about that.

Thanks,

David
