Why is there an extra line for the .toUpperCase() ?

it felt a bit to much so when I tried to rewrite the lines I came up with the next solution

const shout = prompt("What do you want to shout?"); //const shout= stringToShout.toUpperCase(); const shoutMessage=The message to shout is :${shout.toUpperCase()}!!;

console.log(shoutMessage)

I changed the variable of the first line. and it works but... there is probably a good reason why it has been written on a separate line.

The instruction examples will often separate operations into individual statements for clarity. But when writing your own code, you can get the same results more compactly using techniques like method chaining. In this case you can skip the creation of "stringToShout" completely:

const shout = prompt("What do you want to shout? ").toUpperCase();

The only concern might be if this is part of a larger program and the original input is needed by code later on (or the upper-cased version in your example).

// I also did it last this and it worked.

let stringToShout = prompt("what do you want to shout?"); //let shout = stringToShout.toUpperCase(); let shoutMessage = <h2>the message to shout is: ${stringToShout.toUpperCase()}!!</h2>; console.log(shoutMessage); //alert(shoutMessage);

document.querySelector('main').innerHTML=shoutMessage;

same answer as Steven, but I think it also makes the code easier to read.
