Generally, the reading was a mouthful and would love if we went over it again in class

I’m confused about the labelling of variables as discussed in the Scope reading. When talking about the counter, the reading states "Because this is a global variable, we will declare it with var. Notice that the functions refer to an already existing variable. They do not use let or var in front of it (which would make the variable local).” Does declaring with var make the variable global or local?

Just to clarify, is an event hander just a function that performs an action in response to an event?

I am curious as to why would we need to use event.preventDefault() if we just do not include the link when initially creating the code, if that makes sense? Like why would we create a button with a link if were were just going to use event.preventDefault() to prevent that link from being accessed? Can you please share some example cases?


Can you expand on what exactly is an event object? Is it the same thing as the browser which class the event handler function?

What are wrapped sets exactly, and what do .one() and .some() do/why they are needed?

How are the return objects different when using a jQuery selector vs a plain JavaScript selector?

What's the difference between an attribute and property?

If there are multiple DOM elements and we have to attach an event handler, should we always attach it to the a if there is one? How do we pick to make our webpages as accessible as possible?


Why do you need to create a function to attach a handler instead of just making the handler a property of the item itself

I'm still a little confused about the custom attributes. 

the method one() and some()

I'm still getting used to jquery notation! / No specific questions but I'd like to do some more practice with event handlers! 

strict mode

is there a very simple description for closures? I read the mdn web docs on it and was still a little confused...

My questions has been answered while reading more down the contents! :)
