Grammar - Switch Statement

A switch is a multi-way branch.

The switch statement has fall through behavior therefore the break is important.

If you omit the break from a case, and that case matches or runs, execution will continue to the next case.

color = "green"
switch (color) { 
    case "blue": 
         console.log("blue");
    case "green": 
          console.log("green");
    case "red": 
    case "orange":
         console.log("red or orange");
    default:
         console.log("default");
}

• Result: You will see all console output from the green case

color = "green"
switch (color) { 
    case "blue": 
         console.log("blue");
         break;
    case "green": 
          console.log("green");
          break;
    case "red": 
    case "orange": 
          console.log("red or orange");
          break;
    default:
         console.log("default");
}

• Result: you will see only one output
