PreactJS is a fast 3kB alternative to React with the same ES6 API
First, some background…
PreactJS is developed by Jason Miller — one of my programming heroes. The framework was developed with a goal of providing high performance, memory efficiency and close compatibility with React API with an aim to keep the footprint as small as possible i.e 3kb. Preact is increasingly getting adopted in the community with a bunch of high load websites already using it successfully in production.
