1 JavaScript Counter

A JavaScript counter is a simple but versatile component used for everything from incrementing item quantities in a shopping cart to creating animated 'count-up' statistics on a webpage. Building one is a fundamental exercise in state management and DOM manipulation, where JavaScript listens for events to increase, decrease, or reset a numerical value. The animated count-up effect, often used to display impressive stats, is achieved by using JavaScript to incrementally increase a number over a set duration. This collection features various JavaScript counter examples, from simple increment/decrement buttons to animated counters that activate on scroll.
