Question

I have some working code and eventually end up with multiple returned values. Something like this:

console.log(variableName)
-- var1, var2, var1, var3 etc

How do I write a function to get all those variables that are logged from the variable into an object like this? (Fore every repeat the keys must be incremented/counted).

var obj {
  var1 : 2
  var2 : 1
  var3 : 1
  var4 : 0
}

I guess your variableName var is an array like such :

var variableName = ['var1', 'var2', 'var1', 'var3'];

In which case you could do this :

var obj = {};
$(variableName).each(function() {
    if (this in obj) {
        obj[this]++;
    } else {
        obj[this] = 1;
    }
});
