是什么导致第三行出现此错误？

var products = [{

  "name": "Pizza",

  "price": "10",

  "quantity": "7"

}, {

  "name": "Cerveja",

  "price": "12",

  "quantity": "5"

}, {

  "name": "Hamburguer",

  "price": "10",

  "quantity": "2"

}, {

  "name": "Fraldas",

  "price": "6",

  "quantity": "2"

}];

console.log(products);

var b = JSON.parse(products); //unexpected token o
