JavaScript, Typescript switch statement: way to run same code for two cases?

Question

Is there a way to assign two different case values to the same block of code without copy and pasting? For example, below 68 and 40 should execute the same code, while 30 is

Answer 1

case 68:
case 40:
  // stuff
  break;

Answer 2

Switch cases can be clubbed as shown in the dig.

Also, It is not limited to just two cases, you can extend it to any no. of cases.

Answer 3

You should use:

switch condition {
  case 1,2,3:
    // do something
  case 4,5:
    // do something
  default:
    // do something
}

Cases should be comma-separated.

Answer 4

Just put them right after each other without a break

switch (myVar) {
  case 68:
  case 40:
    // Do stuff
  break;

  case 30:
    // Do stuff
  break;
}

Answer 5

Yes, you just put the related case statements next to each other, like this:

case 40:  // Fallthrough
case 68:
   // Do something
   break;

case 30:
   // Do something different
   break;

The Fallthrough comment is there for two reasons:

• It reassures human readers that you're doing this deliberately
• It silences warnings from Lint-like tools that issue warnings about possible accidental fallthrough.
