I am trying to run with this code block but it does not work

Switch (num1>num2) {
case 0:
  document.write(num2);
  break;
case 1:
  document.write(num1);
 break;
}

• 2 num1>num2 can never match value of either of those cases – charlietfl Commented Aug 11, 2018 at 2:32
• 1 Your code is basically document.write(Math.max(num1, num2)). – Angel Politis Commented Aug 11, 2018 at 2:46

You could use something simple as Math.max(5, 10);

const numOne = 5;
const numTwo = 10;

console.log(`Bigger number is: ${Math.max(numOne, numTwo)}`);

Or if you absolutely 'have to' use switch statement, you can try something like this:

const numOne = 5;
const numTwo = 10;

switch(true) {
    case (numOne > numTwo):
        console.log(`Bigger number is ${numOne}`);
        break;
    case (numOne < numTwo):
        console.log(`Bigger number is ${numTwo}`);
        break;
    case (numOne === numTwo):
        console.log(`${numOne} is equal to ${numTwo}`);
        break;
     default: console.log(false, '-> Something went wrong');
}

Logical operations return boolean on Javascript.

document.write writes HTML expressions or JavaScript code to a document, console.log prints the result on the browser console.

   switch (num1>num2) {
      case true:
          console.log(num1);
       break;
       case false:
           console.log(num2);
       break;
    }

switch (with a lower case s) uses strict parison === so the value of a boolean like 11 > 10 will never === 0 or 1.

You need to test for the boolean if you want to do it this way:

let num1 = 10
let num2 = 20

switch (num1>num2) {
    case false:
      console.log(num2);
      break;
    case true:
      console.log(num1);
     break;
    }
    
    

If for some reason you were given numbers you could explicitly cast them to booleans with something like case !!0: but that starts to get a little hard on the eyes.

If your goal is to find the max of two numbers, Math.max(num1, num2) is hard to beat for readability.

You would just use the greater than / less than inside of the switch statement.

var x = 10;
var y = 20;

switch(true) {
    case (x > y):
        console.log(x);
        break;
    case ( y > x):
        console.log(y);
        break;
}
