TheaterJS is a small JavaScript library that creates typewriter-style typing animations mimicking human behavior, including variable speed, mistakes, and multiple actors. It works in the browser by animating text into DOM elements with scene-based sequencing and event callbacks.

Use cases

• add a typewriter effect to a hero heading
• simulate a chat conversation typing animation on a landing page
• animate multiple characters typing dialogue with mistakes and pauses
• create a typing intro animation for a portfolio site
• loop a typing animation that replays automatically

When to choose

• you need human-like typing with variable speed and typos
• you want multiple actors typing into different DOM elements with event hooks
• you want a tiny dependency-free-feeling library with simple scene API

When to avoid

• you only need a basic typewriter effect and prefer a minimal snippet
• you need complex text animation or timeline features beyond typing
• you need a framework-integrated animation system like GSAP
