SyntaxError 类
- 继承自: <errors.Error>
表示程序不是有效的 JavaScript。
这些错误只能作为代码评估的结果生成和传播。
代码评估可能是 eval
、Function
、require
或 vm 的结果。
这些错误几乎始终表明程序损坏。
try {
require('node:vm').runInThisContext('binary ! isNotOk');
} catch (err) {
// 'err' 将是 SyntaxError。
}
SyntaxError
实例在创建它们的上下文中是不可恢复的,它们只能被其他上下文捕获。
- Extends: <errors.Error>
Indicates that a program is not valid JavaScript. These errors may only be
generated and propagated as a result of code evaluation. Code evaluation may
happen as a result of eval
, Function
, require
, or vm. These errors
are almost always indicative of a broken program.
try {
require('node:vm').runInThisContext('binary ! isNotOk');
} catch (err) {
// 'err' will be a SyntaxError.
}
SyntaxError
instances are unrecoverable in the context that created them –
they may only be caught by other contexts.
