Comparison between two arrays

[MounikaS]

Hi Team,

Can some please help me how to compare 2 arrays and any difference found between we need to store difference values in array3 

     while (cm1.next()) {
			var array2 = req.split(', ');
        gs.info("array2 values" + array2);
        var array3 = [];
        var array4 = [];
            var listOfRequestors = cm1.list_of_requestors.getDisplayValue();
            var array1 = listOfRequestors.split(', ');
            gs.info("array1 values" + array1);

            for (var i = 0; i < array2.length; i++) {
                var trimmedValue = array2[i].trim();

                if (array1[i].indexOf(trimmedValue) !== -1) {
                    gs.info("Value in array2 found in array1: " + trimmedValue);
                    array4.push(trimmedValue);
                } else {
                    gs.info("Value in array2 not found in array1: " + trimmedValue);
                    gs.info("Array1: " + array1.join(', '));
                    gs.info("Array2: " + array2.join(', '));
                    array3.push(trimmedValue);
                }
            }
        }


        gs.info("Array3: " + array3.join(', '));
        gs.info("Array4: " + array4.join(', '));


        this.setAnswer(array3.join(', '));

Every time its going to else block even though if we have same values in both the arrays, can some please help me what i need to update to get only different values

I would use ArrayUtil diff for this: you can do diff for Array 1, Array 2; and then diff for Array 2, Array 1. Then use union to join those two results into your final array of where they do not overlap. https://developer.servicenow.com/dev.do#!/reference/api/vancouver/server_legacy/c_ArrayUtilAPI#r_AU-...

Can you please fix below line?

if (array1.indexOf(trimmedValue) != -1) {
