Javascript 是否有用于抛出异常的else语句？

我不熟悉JavaScript，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，对于

throw

异常，有一种

else

语句

例如

---

有可能吗？

您可能正在查找

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.
}

演示：

finally block怎么样？

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.
}
