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. ­čśë

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
