Using p5.js to create a progressbar .

This is an old tutorial about how to create a progressbar with processing.
To convert to p5.js you need to change the processing source code to javascript.
You can read about this conversion here.
In my example I change all variable types to var and I remove the frame.setTitle.
If you using the processing I.D.E. then you need to change from the right area from java to p5.js.
This will make a index.html file ( don't change this file).
This is the source code for p5.js and is working well:

// example progressbar 
// default variables for progressbar
// start the time for progressbar
var startTime; 
// counter progressbar 
var counter;
// maximum time progressbar
var maxTime; 
// boolean for the end progressbar 
var done; 
// settings for this example
function setup() { 
// set title of window
//frame.setTitle("Example progressbar | free-tutorials.org");
// window size and background color
// p5.js
createCanvas(640,130);
 
//size(640,130);
background(25); 
// set variables of progressbar
counter = 0; 
startTime= millis(); 
maxTime=int(random(1000,1976)); 
done=false; 
//end settings
} 
// draw all text and progressbar
function draw() { 
  // set same background color
  background(255); 
 
  // check end of progressbar fill
  if (counter-startTime < maxTime) {
  counter=millis();
  }  else { done=true;  }
  // create the color for fill progressbar
  fill(110,110,255);
  // no stroke for draw
  noStroke();
  // show all text variables and progressbar
  text("Progress bar blue - size 620", 230, 20); 
  rect(10,30,map(counter-startTime,0,maxTime,0,620), 30 );
  text("counter- startTime "+int(counter- startTime)+" ",10,80);
  text("maxTime "+ int(maxTime) +  " ", 10,100);
  text("map converted counter-startTime"+ int ( map(counter-startTime,0,maxTime,0,200)), 10,120);
  noFill();
 
  }
// reload the draw of progress bar 
function mousePressed () { 
  if (done) { counter = 0; startTime= millis();
  maxTime=int(random(1000,1976)); 
  done=false;
  }
}
