Why are we using - const main = document.queryselector('main'); ? Instead can we write whole statment in the end?

Instead can we write document.queryselector('main').innerHTML(...) i.e the entire statement together in the end.

Don't really understand the importance of const main in here

Hey, you are right that you can write it all together. Declaring the variable may just make it easier to understand or provide less errors in the future. If you have to use main in the future, you don't have to continue writing document.querySelector('main') each time.

You CAN do it, Just we are looking to make it the shortest possible so if you make a variable from this main element then when ever you want to select it you just write the variable name and it selects the element
