Q:

pug - array output via each without commas

I have this following pug array and let it execute in an each.  The problem is the values are listed with commas.  I want it without commas. 
I could write the array in the each like each x, y in {'value1': 'value2', ...} but that isnt comfortable. 
The current code: 
-
  var starWars = {
    "people": [
      "Yoda",
      "Obi-Wan",
      "Anakin"
    ],
    "rank": [
      "master",
      "master",
      "knight"
    ]
  }
each person, rank in {starWars}
  p= person.people
  p= person.rank

Output: 
Yoda,Obi-Wan,Anakin

master,master,knight

A:

The = character after the tag p is for buffered code.  Any JavaScript expression is valid input and will be converted to a string before being printed. 
So when you put in an array, it is converted to the string representation of that array which is to separate each element with a comma. 
Add a .join(" ") after each array to convert them to a string yourself and delimit them by space rather than comma:
each person, rank in {starWars}
  p= person.people.join(" ")
  p= person.rank.join(" ")

Output with my changes:
Yoda Obi-Wan Anakin
master master knight
