P5.js or Javascript random value generation with no repeat

Question

I am trying to create 5 circle shapes with randomly generating filled color from an array. But since I hard coded 5 individual random() generation. Sometimes the randomly generated colors between the circles still being the same. I am not sure how to make it so the colors for each circles will not have same color (the same random result) :

function setup() {
  createCanvas(400, 700);
  noLoop();
}

function draw() {
  background(220);
  filled = ['PapayaWhip','PaleVioletRed','Lavender','LightGreen','Coral', 'CadetBlue','Azure','HoneyDew','LightBlue','Thistle','SlateBlue','RosyBrown','SteelBlue','OrangeRed'];
  randcol1 = filled[floor(random() * filled.length)];
  randcol2 = filled[floor(random() * filled.length)];
  randcol3 = filled[floor(random() * filled.length)];
  randcol4 = filled[floor(random() * filled.length)];
  randcol5 = filled[floor(random() * filled.length)];
  fill(randcol1);
  circle(width/2,100,100);
  fill(randcol2);
  circle(width/2,200,100);
  fill(randcol3);
  circle(width/2,300,100);
  fill(randcol4);
  circle(width/2,400,100);
  fill(randcol5);
  circle(width/2,500,100);
}

By the way may I also ask, is there anyway to perform individual random generation without repeating 5 lines of random()?
Thanks
