How about beginning a JavaScript count with a randomly generated number?

As I work on developing this code, I am faced with a challenge:

/**
 * Increment value with random intervals.
 * @param {string} id - Id of DOM Element.
 * @param {number} start - Start counter value. Applied immediately- 
 * @param {number} end - End counter value.
 * @duration {number} duration - Max duration of one iteration in ms.
 */
function animateValue(obj, start, end, duration) {
  let current = start;
  obj.innerHTML = current; // immediately apply start value
  const setIncrOut = () => {
    let time = Math.random() * 1000;

    setTimeout(function() {
      if (current < end) {
        current += 1;
        obj.innerHTML = current;
        setIncrOut(time)
      }
    }, time);
  }
  setIncrOut();
}

document.querySelectorAll(".incr").forEach(obj => animateValue(obj, 10, 100000000));
<div class="incr"></div>

The block of code above always initiates from the number 10.

I am working towards being able to randomly select a starting point between 0 and 10 each time the script runs.

I attempted adding:

let srandom = Math.random();

and then making changes to:

document.querySelectorAll(".incr").forEach(obj => animateValue(obj, srandom, 100000000));

However, this resulted in the script not displaying anything.

I believe there may be an error in my approach.

Your assistance is greatly appreciated.

Answer №1

One approach is to create a function that accepts two parameters (min and max) and generates a random number within that range.

function generateRandomNumber(min, max) {
  min = Math.ceil(min);
  max = Math.floor(max);
  return Math.floor(Math.random() * (max - min) + min); // The maximum value is excluded while the minimum value is included
}

Answer №2

For a tutorial on how to generate random numbers within a specific range, check out this helpful guide. This example demonstrates obtaining a random number between 0 and 10:

let randomNumber = Math.floor(Math.random() * 11);
