如何在 JavaScript 中记录没有堆栈跟踪的错误消息？

Question

我想在不退出程序的情况下记录发生的错误，因此我将可能会引发错误的代码包含在try-catch这样的块中

try
{
    let query = parseStatement(input); // might throw an error
    console.log(query);
}
catch (err)
{
    console.error(err); // logs the entire error with stack trace
}
finally
{
    this.prompt();
}

我想获得的输出是没有整个堆栈跟踪的错误消息。大致如下：

Error: Missing semicolon at the end of statement: <statement>

并不是

Error: Missing semicolon at the end of statement: <statement>
    at error (/home/nic/dev/nodedb/src/errors.js:5:11)
    at Function.tokenize (/home/nic/dev/nodedb/src/tokens.js:53:13)
    at parseStatement (/home/nic/dev/nodedb/src/sql.js:35:24)
    at Shell.onData (/home/nic/dev/nodedb/src/shell.js:49:25)

从文档中：

该Error对象有一个.message属性，因此不必打印整个错误，只需

console.error(error.message);
