You have to concatenate a variables with strings. You cannot write firstName in quotes. When you write it in quotes it's treated just like string 'firstName' without any refer to variable firstName.

So if you want to concatenate variables with strings you have to write sth like this:

let msg = firstName + ' ';

In this example above you have value from firstName ( because it's without quotes so it refers to variable with this name) and then you have added a space (because this sign is added with quotes).

If we change it to

let msg = 'firstName' + ' ';

Now in msg we have just series of signs: 'firstName '. firstName is in quotes so it's treated just like normal series of signs (without any refer to any variable).

And you have to remember to add colon before role.

BTW what is this?

console.log = msg

Shouldn't it be?

console.log (msg)
