Display values as List on a Multiple Line text variable

[Insider]

I have a variable called approvals.

On which i show all the list of approvals who approved that current case.

as of now i am seeing data as 

approver1. approver2. approver3. approver4

But i want the data to be shown as 
approver1
approver2

approver3

approver4

for info i am using an array to store this data, so could it be possible to achieve this functionality with in array? should i take a new approach?

Please suggest

One approach is to use the join() method of the array to convert the array into a string with each element separated by a delimiter (e.g., a comma). Then, you can use the replace() method to replace the delimiter with a line break character (i.e., '\n').

// Assuming 'approvals' is an array containing the list of approvers
var approverList = approvals.join(', '); // Convert the array to a string with comma-separated values
approverList = approverList.replace(/,\s/g, '\n'); // Replace the comma with a line break character
gs.info(approverList); // Display the formatted approver list in the ServiceNow system log

This code will replace all occurrences of the comma followed by a space with a line break character. The resulting string will be displayed in the ServiceNow system log.

Alternatively, you can use a loop to iterate through the array and concatenate each element with a line break character.

// Assuming 'approvals' is an array containing the list of approvers
var approverList = '';
for (var i = 0; i < approvals.length; i++) {
  approverList += approvals[i] + '\n'; // Concatenate the current approver with a line break character
}
gs.info(approverList); // Display the formatted approver list in the ServiceNow system log

This code will loop through the array and concatenate each element with a line break character.

I am currently using,

 var approversList = [];

    while (gr.next()) {

//gs.addInfoMessage(gr.state);

if(gr.state == 'approved'){

        approversList.push(gr.approver.getDisplayValue() + ' - ' + gr.short_description) + ' ';

    }

}

    var rec = new GlideRecord('x_gskgs_gsf_case_1_finance_procurement_case');

    rec.get(current.document_id);

    rec.variables.first_approver = approversList.toString();

    rec.update();

Where in the end i need the list of approvers on first_approver field but i am getting them side by side.

You can pass '\n' into the variable for a new line, so when you are populating the variable with the array, if it's a string and not an actual array type script variable I would try to first split the string into an array on the . or , that it currently contains, then join it specifying \n instead.  If that doesn't work split the string into an actual array then use a for loop to write each member to a new string script variable, followed by \n in each iteration, then populate the Mutli Line Text variable with the string.
