v1.2.0

put default value to metaArr

• maybe the giving key names are the same with default key name,

like the programmer named the SPAname as SPAname in the JSON file and that is the default.

• so no need to pass it in metaArr, but if he did that in ast version he'll get errors, but now i solved it by putting the default inside this line:

function jsonRead(jsonpages, metatagArr = ["SPAname", "SPAurl", "SPAtitle"])
