Javascript Switch case statement : fall-through all cases when expression is 'all'

How can I implement this behavior in JavaScript Switch Statements

expression = 'all' or '1' or '2' 

switch (expression)
{
   case "all" : print case 1 and case 2 
      
   case "1" : print only case 1 

   case "2" print only case 2
}

How can I do that? If there’s no way to do something like that in JavaScript, I want to know an alternative solution.

>Solution :

You could take two condition instead.

function fn(expression) {
   if (expression === '1' || expression === 'all') console.log(1);
   if (expression === '2' || expression === 'all') console.log(2);
}

fn('1');
console.log('----------');
fn('2');
console.log('----------');
fn('all');
