JavaScript Create the Loop – One Solution

displaying the code

trying to understand why we dont do just basic displaying this way;

message = <h1>You guessed the number! It was ${randomNumber}.</h1>; document.querySelector("main").innerHTML = message

I can see in the video they create variable on the top like this followed by code in the end of the document

const main = document.querySelector('main'); //this is on the top;

main.innerHTML = <h1>You guessed the number! It was ${randomNumber}.</h1>; //this in on the button

Does it make any difference? when we display the code your way and why did we created variable?

The variable has no effect on delivering the message to the page, but it's useful for setting which message will be shown. Before the last program improvement, only one message was being shown so the variable wasn't needed.
