Answer 1

In most programmimg languages the variable scope exists or visible within the braces {} only.

Therefore if you want to access it from the scope outisde, then you can DECLARE it outside as well and ASSIGN it within the scope. 😉

Just declare variable outside and change inside.
You're done.

var a

$("btn").click(function(){
a=0
a++
})

or in ES6 style
let a
$('btn').click( () => {
a=0
a++
}
//any other actions with a anywhere you want
