在 JavaScript 中，如何访问对象数组中的对象属性？

transactions.map((transaction, index) => {
    if(transaction.hasOwnProperty("company_name")){
       console.log(transaction.company_name);
    }
    if(transaction.hasOwnProperty("company_name")){
       console.log(transaction.project_name);
    }
    if(transaction.hasOwnProperty("tester_transaction")){
       console.log(transaction.tester_transaction.amount);
    }
    if(transaction.hasOwnProperty("tester_transaction")){
       console.log(transaction.tester_transaction.status);
    }
});

不要忘记检查该属性是否存在。
