Number Countup Animation With Vanilla JavaScript – Animated Counter

Description:

Just another animated counter JavaScript library for animating counting up to a given number.

How to use it:

1. Add the CSS class counter to the container which holds the initial value, and then specify the number to which the counter counts up in the data-target attribute:

<div class="counter" data-target="300000">1000</div>
<div class="counter" data-target="200000">0</div>

2. Apply the countup animation to the element and done.

// Selector
const counters = document.querySelectorAll('.counter');
// Main function
for(let n of counters) {
  const updateCount = () => {
    const target = + n.getAttribute('data-target');
    const count = + n.innerText;
    const speed = 5000; // change animation speed here
    const inc = target / speed; 
    if(count < target) {
      n.innerText = Math.ceil(count + inc);
      setTimeout(updateCount, 1);
    } else {
      n.innerText = target;
    }
  }
  updateCount();
}
