Hi, > What will happen if some of those values will be null ? For example > styleable.style ?
Styleable could be I guess but there wasn’t a null check for it before. Styable.style is unlikely to be null. All test still pass and I’ve tested this with several applications and it never has a null value and there no code in the framework that sets it to null that I could see. The code is significantly faster. In the other case you are looking a property that's likely to be a string /number so it will exist or not exists, comparing via == or != or if(o) is dangerous as it matches or doesn’t match all sort of things you may not expect. But as AS and JS behaves a little differently here it would be good to have a discussion on how we should treat null/undefined. Thanks, Justin
