错误类型
SyntaxError
什么地方出了错？
JSON.parse()将字符串解析为JSON。该字符串必须是有效的JSON，如果遇到不正确的语法，将会抛出此错误。
例子
JSON.parse() 不允许尾随逗号
两行都会抛出一个SyntaxError：
JSON.parse('[1, 2, 3, 4,]'
JSON.parse('{"foo": 1,}'
// SyntaxError JSON.parse: unexpected character
// at line 1 column 14 of the JSON data
省略尾部的逗号来正确解析JSON：
JSON.parse('[1, 2, 3, 4]'
JSON.parse('{"foo": 1}'
属性名称必须是双引号字符串
你不能在属性周围使用单引号，比如'foo'。
JSON.parse("{'foo': 1}"
// SyntaxError: JSON.parse: expected property name or '}'
// at line 1 column 2 of the JSON data
而是写下“foo”：
JSON.parse('{"foo": 1}'
前导零和小数点
您不能使用前导零，如01，小数点后面必须至少有一位数字。
JSON.parse('{"foo": 01}'
// SyntaxError: JSON.parse: expected ',' or '}' after property value
// in object at line 1 column 2 of the JSON data
JSON.parse('{"foo": 1.}'
// SyntaxError: JSON.parse: unterminated fractional number
// at line 1 column 2 of the JSON data
而是只写1而不是零，小数点后至少使用一位数字：
JSON.parse('{"foo": 1}'
JSON.parse('{"foo": 1.0}'
