Hello, I am getting a bit confused here… I need to count how many times the word imagine shows up in the array but I do not know how to create the counter so it works and is printed… thank you! Any guidance is very welcomed.

var parrafo = "Imagine there's no heaven | It's easy if you try | No hell below us | Above us only sky | Imagine all the people | Living for today | Imagine there's no countries | It isn't hard to do | Nothing to kill or die for | And no religion too | Imagine all the people | Living life in peace";
var parrafo_array;
var contador;

function setup() {
  createCanvas(1024, 768);
  background("white");
  fill(50);
  textSize(20);
  contador = 0;

 for (var i=0; i< 61; i++) {
   if (parrafo [i] = true) {
   contador = contador + 1;
   } if else {
   contador = contador;
   }
 text(contador, 10, 10); 
}

You’re using the assignment operator = instead of the equality operator ==:

Also you still need to splitTokens() your lyrics string so it becomes an array of words.

Only then you can count each word inside that array which matches string “imagine”.

Why not just using RegEx and do something like (just as example):

const wordCounter = (myString,mySearchString) => ((myString).match(new RegExp('\\b'+mySearchString+'\\b',"g")) || []).length;

let pinfo;
let itext;
let isearch;

function setup() {
  noCanvas();
  createElement("label").html("Search String: ");    
  isearch = createInput("Imagine");
  createElement("br");
  createElement("label").html("Text To Search: ");
  itext   = createInput("Imagine there's no heaven | It's easy if you try | No hell below us | Above us, only sky | Imagine all the people | Livin' for today | Ah | Imagine there's no countries | It isn't hard to do | Nothing to kill or die for | And no religion, too | Imagine all the people | Livin' life in peace | You | You may say I'm a dreamer | But I'm not the only one | I hope someday you'll join us | And the world will be as one | Imagine no possessions | I wonder if you can | No need for greed or hunger | A brotherhood of man | Imagine all the people | Sharing all the world | You | You may say I'm a dreamer | But I'm not the only one | I hope someday you'll join us | And the world will live as one");  
  itext.input(function() {
      pinfo.html("The word " + isearch.value() + " was found " +   wordCounter(this.value(),isearch.value()) + " time(s)");  
  });  
  pinfo = createP();  
}
