SyntaxError
JSON.parse() converte uma string para JSON. A string precisa ser um JSON vlido e retornar esse erro caso a sintaxe esteja errada.
JSON.parse() no permite vrgulas direitaAs duas linhas retornaro um 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
Retire as virgulas sobrando para converter o JSON corretamente:
JSON.parse("[1, 2, 3, 4]");
JSON.parse('{"foo": 1}');
Voc no pode usar aspas simples em propriedades, exemplo: 'foo'.
JSON.parse("{'foo': 1}");
// SyntaxError: JSON.parse: expected property name or '}'
// at line 1 column 2 of the JSON data
Em vez disso use "foo":
JSON.parse('{"foo": 1}');
Voc no pode usar zeros esquerda, como 01, e pontos decimais precisam ser seguidos de pelo menos um digito.
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
Em vez disso, use o 1 sem o zero, e pelo menos um digito aps um ponto decimal:
JSON.parse('{"foo": 1}');
JSON.parse('{"foo": 1.0}');
