Hi,
In runtime-js SkeletonJson.readSkeletonData parameters were a parsed json object and a skeleton name.
In runtime-ts this is changed to only take a json string and parse object by itself.
This is just one interface change between runtime-js and runtime-ts are these differences deliberate?
It actually allows both a JSON string, and a parsed JSON object. See spine-runtimes/SkeletonJson.ts at master · EsotericSoftware/spine-runtimes · GitHub
Due to me being new to git i did not get the latest with git pull 
sorry for the inconvenience.
No worries, git is a mystery to me as well since forever
