**Solution**: If you are creating HTML that absolutely requires leading text, use `$.parseHTML` and pass the results to `$()`.

### JQMIGRATE: jQuery.fn.andSelf() replaced by jQuery.fn.addBack()

**Cause**: The `.andSelf()` method has been renamed to `.addBack()` as of jQuery 1.9 to better reflect its purpose of adding back the previous set of results.

**Solution**: Replace any use of `.andSelf()` with `.addBack()`.

### JQMIGRATE: jQuery.fn.size() is deprecated; use the .length property

**Cause**: The `.size()` method returns the number of elements in the current jQuery object, but duplicates the more-efficient `.length` property which provides the same functionality. As of jQuery 1.9 the `.length` property is the preferred way to retrieve this value.

**Solution**: Replace any use of `.size()` with `.length`.
