Comparing two arrays : get the one which is not present in another array

[dhathrianoop]

I have the below script :

Compare two arrays 'arrLaIpAddress' and 'arrCmdbIpAddress', if 'arrLaIpAddress' is not present in 'arrCmdbIpAddress', get those IP address in 'arrIpAddress'.

var ipAddress;
var arrLaIpAddress = [];
var arrCmdbIpAddress = [];
var arrIpAddress =[];
var grDiscoveryLogAnalysis = new GlideRecord('x_qune_da_log_analysis'); // UPDATE TABLE
grDiscoveryLogAnalysis.addQuery('troubleshooting.number', 'TRBL0001033');
grDiscoveryLogAnalysis.query();

while (grDiscoveryLogAnalysis.next()) {
//gs.log(grDiscoveryLogAnalysis.device_ip_address);

ipAddress = grDiscoveryLogAnalysis.getValue('device_ip_address');
arrLaIpAddress.push(ipAddress);
}
//gs.log(arrLaIpAddress);

var grCmdb = new GlideRecord('cmdb_ci');
grCmdb.addNotNullQuery('ip_address');
grCmdb.query();
while (grCmdb.next()) {
var cmdbIpaddress = grCmdb.ip_address;
arrCmdbIpAddress.push(cmdbIpaddress+'\n');

}

//gs.log(arrCmdbIpAddress);

for(var y = 0; y < arrLaIpAddress.length; y++){
if(arrCmdbIpAddress.indexOf(arrLaIpAddress[y]) < 0){
arrIpAddress.push(arrLaIpAddress[y]+'\n');
}
}
gs.log(arrIpAddress);

@dhathrianoop 

please check script below and it gave me the difference as 1

var arrayUtil = new ArrayUtil();

var a = [1,2,3,4];

var b = [2,3,4,5];

gs.info(arrayUtil.diff(a, b));

Output:
