Ola is a small JavaScript library for smoothly interpolating (tweening) numbers in real time. It supports single numbers, named multi-dimensional values, and arrays of values, updating asynchronously so reads always return the current animated value.

Use cases

• smoothly animate a number or position over time in the browser
• interpolate multi-dimensional values like x/y coordinates for a moving element
• tween hundreds of independent values efficiently for canvas or DOM animations
• replace manual easing/tweening code with a simple set-and-read API

When to choose

• you need lightweight realtime numeric interpolation rather than a full animation framework
• you want to animate many independent values (arrays, objects) with minimal overhead
• you prefer a tiny dependency-free library usable via npm or CDN

When to avoid

• you need CSS/DOM element animations, keyframes, or timelines - use a full animation library instead
• you need easing functions, springs, or complex choreography beyond simple interpolation
• your project is not JavaScript/browser-based
