Question

(function() {

    var sample = "sample1";

    (function() {

        // set sample variable 
        sample = "sample2";

        (function() {

            // set sample variable
            sample = "sample3";
        }());
    }());



    console.log(sample); // "sample3"
}());

so; sample name @variable console.log results “sample3”; How do I get the first variable? “sample1” ??

console.log(sample); // --> "sample1" ?? 

thank You.

You can declare an independent sample variable in each scope:

(function() {

    var sample = "sample1";

    (function() {

        // set sample variable 
        var sample = "sample2";

        (function() {

            // set sample variable
           var sample = "sample3";
        }());
    }());

console.log(sample); // "sample1"
}());
