QUESTION
One of the key feature of const
in javascript
is that, const
variable can not declare twice.
So in this code that is grabbed from [this][1] link
ANSWER
Answered 2021-May-28 at 09:41as far as I know variables in functions are always temporary if they are declared in the function scope. So even though it's a const it's still temporary since it's declared inside a function. You however would not be able to declare a different variable with the same identifier. so saying const x and later on saying let x isn't possible. If you had identified the const x outside of the function scope you wouldn't be able to set a variable with the same identifier in the function scope.
QUESTION
I am currently learning SignalR
with .Net
MVC and following a tutorial to work on a simple app. Right now it is working alright, but I am having trouble understanding some part and also if possible, want to sort of enhance it.
Right now the app is working as when a user clicks on a seat, it reserves it. And there is no going back. I want to implement like a toggle, where if the user wants to change seat, he gets to unreserve his selected seat, and then be free to reserve another one. I am not being able to do it with myHub.server.selectSeat(userId, $(this).toggleClass(settings.selectingSeatCss));
. Whenever I click on a seat, it gives me this error in the Dev tools
...Uncaught: Converting circular structure to JSON
ANSWER

function instead of just using toggleClass
