Now a days you can do

    const str = Java$$Java$$jQuery$$Java$$jQuery$$Java$$Java$$Java$$Hibernate$$Java$$Java$$Spring$$Instagram$$jQuery$$jQuery$$;

    

    var result = str.split($$).reduce(function(acc, curr) {

    curr &&  (acc[curr] = (acc[curr] + 1) || 1);

    	return acc

    }, {});

    console.log(result);
