Summary;

Loop	Best for
`for`	repeating a fixed number of times
`while`	repeating until a condition changes

while → you control the counter manually
for   → the counter is built into the loop

Q: Counter based while loop is similar to for loop. is that correct?

Yes — that’s basically correct.

A counter-based while loop and a for loop often do the same job: repeat something a certain number of times using a counter variable.

The difference is mostly how the code is organized.

1. Counter-based `while` loop

In a while loop, you must create and update the counter yourself.

Example (p5.js):

let i = 0;

function setup() {
  createCanvas(400, 200);
}

function draw() {
  background(220);

  let x = 20;

  while (i < 5) {
    ellipse(x, 100, 20, 20);
    x = x + 60;
    i = i + 1;
  }

  noLoop();
}

What happens

i starts at 0
Check i < 5
Draw circle
Increase i
Repeat

2. `for` loop (same logic)

1. Counter-based while loop

What happens

2. for loop (same logic)

1. Counter-based `while` loop

2. `for` loop (same logic)
