Bold Text within Arcade Expression

[MelissaSalich]

I have an expression in Arcade and I want to bold only one part of it. 

$feature["SPACEID"] + TextFormatting.NewLine + "Wheel Chair Stations: " + $feature.WCHAIRACCESS + TextFormatting.NewLine + "Barrier Free Door: " + $feature.BARRFREEDOOR

How do I bold only SPACEID?

I would do 2 different label classes and set the position for the label with the label styling.

Or, an easier way (assuming you're just doing text in a pop-up) might be to use an Arcade element. You have access to all the HTML formatting so making part of your text bold is easy, peasy.
