Question shows a lack of research or code attempt to resolve issue. You are expected to have at least tried something and if you did post the code that wasn't working — charlietfl

Loop over one of the arrays and use the index to access the other, save in an object

var result = {};

keys.forEach(function(item, index) {
   result[item] = values[index]; 
});

A very simple loop should suffice, copying the values & keys at each index into a new object:

var finalOutput = {};
for(var i=0, j=keys.length; i<j; i++) {
    finalOutput[keys[i]] = values[i];
}

Note: You shouldn't use final as a variable name as it is a reserved future keyword
