Labelled block and switch statements

[kaleidawave]

You can do the following in JS

label1: {
	console.log("here");

	if (condition) {
		break 'label1;
	}

	console.log("here");
}

break is 50% handled for for loops. The following needs to be handled in a similar manner. It might require a new Event variant to handle breaks inside.

Additionally solving this would make supporting switch statements simple.

switch (x) {
	case "x": 
		thing1();
	case "y":
		break;
	case "z":
		thing2();
}

Apart from the fact you lift all the variable identifiers

swtch: {
	if (x === "x") {
		thing1();
	}
	if (x === "y") {
		break 'swtch;
	}
	if (x === "y") {
		thing2();
	}
}

No idea what happens for continue and I am afraid to find out

And another case for #124 🤦‍♀️🤦‍♀️🤦‍♀️🤦‍♀️🤦‍♀️

switch(true) {
    case false:
        const x = 2;
    case true: 
        console.log(x)
}
