Add quotation at the start and end of each line in Notepad++

You won’t be able to do it in a single replacement; you’ll have to perform a few steps. Here’s how I’d do it:

1. Find (in regular expression mode):

   (.+)
   

   Replace with:

   "\1"
   

   This adds the quotes:

   "AliceBlue"
   "AntiqueWhite"
   "Aqua"
   "Aquamarine"
   "Azure"
   "Beige"
   "Bisque"
   "Black"
   "BlanchedAlmond"
   

2. Find (in extended mode):

   \r\n
   

   Replace with (with a space after the comma, not shown):

   , 
   

   This converts the lines into a comma-separated list:

   "AliceBlue", "AntiqueWhite", "Aqua", "Aquamarine", "Azure", "Beige", "Bisque", "Black", "BlanchedAlmond"
   

3. Add the var myArray = assignment and braces manually:

   var myArray = ["AliceBlue", "AntiqueWhite", "Aqua", "Aquamarine", "Azure", "Beige", "Bisque", "Black", "BlanchedAlmond"];
