Chapter 6.3: Creating Errors

In GLang, you can create your own errors using the uhoh built-in. It takes a msg (message) as its argument, outputs the error, immediately halting execution.

uhoh("Something is broken...");

This can be super handy for type-checking or validating function arguments before something explodes later on.

func x(arg1) {
    if not isstring(arg1) {
        uhoh("expected 'arg1' to be a string type");
    }
}

x(1);
