javascript - 是否有抛出异常的 else 语句？

Question

我是 JavaScript 新手，但一般来说对编程/脚本并不陌生，我有一个关于throw异常的查询。

所以，我想知道的是有一种例外else声明。throw

例如

// More code above
try
{
    if(i=="something") {
        throw "'i' equals 'something'."
    }
    else
    {
        throw "'i' doesn't equal 'something'."
    }
}
// More code here

这样的事情可能吗？

您可能正在寻找finally关键字

try
{
    if(i=="something") {
        throw "'i' equals 'something'."
    }
    else
    {
        throw "'i' doesn't equal 'something'."
    }
} catch( ex ) {
    // your exception handling code
} finally {
    // Statements that are executed after the try statement completes.
}
