Arcade: TextFormatting.NewLine

Is there a way to create spacing in-between line breaks for an Arcade expression?

Below is a script

//field in the point address feature layer
var geoid = $feature.GEOID

//WV Fixed Dec2020 v1 is the related table
var fcc = FeatureSetById($map, /* WV Fixed Dec2020 v1 */ "17f74d21aeb-layer-4")

//filter function to match all addresses that share the same blockcode
var filterStatement = "BlockCode = @geoid"

//variable for related table
var providers = Filter(fcc, filterStatement)

//build out pop-up
var popupResult = ''
for (var f in providers) {
popupResult += " - " + f.ISP + " (" + f.Technology + ") " + " (" + f.Service + ") " + TextFormatting.NewLine
}

return popupResult

The final result currently looks like this:

Desired outcome would look like this:

- Frontier Communications Corporation | Frontier Communications Corporation | Frontier Communications Corporation (Asymmetric xDSL) (Residential | Commercial)

- Frontier Communications Corporation | Frontier Communications Corporation | Frontier Communications Corporation (ADSL2, ADSL2+) (Residential | Commercial)

- Frontier Communications Corporation | Frontier Communications Corporation | Frontier Communications Corporation (VDSL) (Residential | Commercial)

- ViaSat, Inc. | Viasat Inc | ViaSat, Inc. (Satellite) (Residential | Commercial)

- UNITED STATES CELLULAR CORPORATION | United States Cellular Corporation | Telephone and Data Systems, Inc. (Fixed Wireless) (Residential)

- GCI Communication Corp. | GCI Communication Corp. | GCI Holdings LLC (Satellite) (Commercial)

- HNS License Sub, LLC | HughesNet | Hughes Network Systems, LLC (Satellite) (Residential | Commercial)

- VSAT Systems, LLC. | VSAT Systems, LLC. | VSAT Systems, LLC (Satellite) (Residential | Commercial)

Thanks!

First things first: don't forget about the "code sample" button on here.

Second, you can definitely add line breaks like that. You could just take the current script and include two newlines at the end of your popupResult += ... line.

However, this method is a bit less than idea, because it creates space at the end of your popup that you don't need. I would suggest making use of the Concatenate function. Instead of building the popup string in your loop, just append to an array, and then generate the string from that.

Also, I like to suggest the use of template literals whenever possible, because it's just easier to read than all those + and " characters.

//field in the point address feature layer var geoid = $feature.GEOID //WV Fixed Dec2020 v1 is the related table var fcc = FeatureSetById($map, /* WV Fixed Dec2020 v1 */ "17f74d21aeb-layer-4") //filter function to match all addresses that share the same blockcode var filterStatement = "BlockCode = @geoid" //variable for related table var providers = Filter(fcc, filterStatement) var out_arr = [] //build out pop-up for (var f in providers) { Push( out_arr, `- ${f.ISP} (${f.Technology}) (${f.Service})` ) } // Return all items in array, separated by two lines each return Concatenate(out_arr, '\n\n')

And here's me testing it on a sample layer:

Well this was great insight. Thank you Josh!
