这段简单的JSON出了什么毛病？

Question

var bio = { "name": "QUBE", "role": , "welcomemessage": , "biopic": , contacts = { "mobile": , "email": , "github": , "location": , } "skill": [],}在https://jsonlint.com/检测Error: Parse error on line 1:var bio = { "name":^Expecting 'STRING', 'NUMBER', 'NULL', 'TRUE', 'FALSE', '{', '[', got 'undefined'实在不知道哪里出了问题。。

Answer 1

json直接就是{}[]包裹，不是用var 去声明

Answer 2

value也不能为空吧。。。至少写个null或者 ""

Answer 3
