Error handling

Try-catch

try {
    // do something
}
catch (err) {
    // catch the error
}

// todo

Throw an exception

throw 'error'

You can throw any value as exception.

throw null
throw true
throw 123

Error object

We do not provide a class like "Error" in a few languages. So the default system error was thrown is a map.

main.no

try {
    null()    // attempt to call null
} catch (e) {
    puts e
}

output

{
    message: 'Appempt to call a null value.',
    stack: 'in main.no (2:9)'
}

You must provide your own error objects and handle it manually.
