Answer 1

 // Converts String To Array
        var SampleString= Array.from("saleem");

        // return Distinct count as a object
        var allcount = _.countBy(SampleString, function (num) {
            return num;
        });

        // Iterating over object and printing key and value
        _.map(allcount, function(cnt,key){
            console.log(key +":"+cnt);
        });

        // Printing Object
        console.log(allcount);

    
Set the variable to different value and then try...
