        "Richard Helm",
        "Ralph Johnson",
        "John Vlissides"

```



# Part 1：null false true

语法：

```json
JSON-text = ws value ws
ws = *(%x20 / %x09 / %x0A / %x0D)
value = null / false / true 
null  = "null"
false = "false"
true  = "true"
```

“*”表示：重复0次，1次，2次，或多次

# Part 2：number

语法：

```json
number = [ "-" ] int [ frac ] [ exp ]
int = "0" / digit1-9 *digit
frac = "." 1*digit
exp = ("e" / "E") ["-" / "+"] 1*digit
```

完成这部分后，value的语法变成了：value = null / false / true / number
