js source code

Hello,
    Running js code in attachment, output in ChakraCore, V8 and SpiderMonkey is:

["",""]
r.lastIndex=0
RegExp.${_,1,...,9}=["a","","","","","","","","",""]
BT_FLAG

    But, JavaScriptCore is:

["",""]
r.lastIndex=0
RegExp.${_,1,...,9}=["","","","","","","","","",""]
BT_FLAG
