Remove duplicate values Array

[Harish KM]

var res=[];

var changeArr='';

var changeTask = new GlideRecord('change_task');

changeTask.addQuery('change_request', current.sys_id);

changeTask.query();

while (changeTask.next())

  {

  changeArr+=','+changeTask.assignment_group.manager;

  res.push(current.u_technical_approver_users=changeArr); //

}

here i am getting duplicate values,

one group can have 2 managers with the same name. i want to eliminate the duplicate

can any one suggest?

Why dont you use arrayUtil,

Its very efficient

Unique is also a function that you just have to call

I tried with ArrayUtil, Not able to find correct syntax,

Can u explain? how to use

[Chuck Tomasi · Accepted solution]

I have converted your changeArr from a string to an array for easier processing (and no leading/trailing comma). To make it a comma separated string use arrayName.join(',');

var res=[];

var changeArr=[];

var changeTask = new GlideRecord('change_task');

changeTask.addQuery('change_request', current.sys_id);

changeTask.query();

while (changeTask.next())

  {

  changeArr.push(changeTask.assignment_group.manager);

  res.push(current.u_technical_approver_users=changeArr); //

}

var au = new ArrayUtil();

var newChangeArr = au.unique(changeArr);

var newRes = au.unique(res);

Can we use ArrayUtil() in scoped app transform map scripts ?
