If the fallthrough is intentional in the code, there is no way to indicate this intent in the language. It's considered a best practice to always indicate when a fallthrough is intentional using a comment which matches the /falls?\s?through/i regular expression.

Bad Practice

switch(foo) {
    case 1: doSomething();
    case 2: doSomethingElse();
}

Recommended

switch(foo) {
    case 1:
        doSomething();
        break;
    case 2:
        doSomethingElse();
}

function bar(foo) {
    switch(foo) {
        case 1:
            doSomething();
            return;
        case 2:
            doSomething();
    }
}

switch(foo) {
    case 1:
        doSomething();
        throw new Error("Boo!");
    case 2:
        doSomething();
}

switch(foo) {
    case 1:
    case 2:
        doSomething();
}

switch(foo) {
    case 1:
        doSomething();
        // falls through
    case 2:
        doSomething();
}
