Definition
Render is a unified cloud application platform that lets developers deploy web services, static sites, background workers, cron jobs, and managed databases directly from a Git repository without managing servers.
Overview
Founded in the late 2010s, Render positioned itself as a modern alternative to Heroku, aiming to combine the simplicity of platform-as-a-service deployment with more transparent pricing and stronger performance defaults after Heroku scaled back its free tier. Developers connect a GitHub or GitLab repository, and Render automatically detects the build and runtime for many languages (Node.js, Python, Ruby, Go, and more) or builds directly from a Docker image, then deploys it behind automatic HTTPS and a global CDN. It supports zero-downtime deploys, preview environments generated automatically for pull requests, autoscaling, and managed PostgreSQL and Redis instances that sit alongside the deployed application services. Render competes with Vercel, Netlify, and similar platforms, and is frequently chosen by small teams and startups migrating full-stack apps and APIs off Heroku, thanks to its native Docker support and built-in database hosting.

React Hooks let function components manage state and side effects: useState stores changing data, and useEffect runs code after render for fetching and timers.
Read More ProgrammingHow React Works: Rendering, State, and Reconciliation
React runs your components to produce a description of the UI, compares it with the previous description, and applies the differences to the DOM. Learn the render-and-commit cycle, why state updates are batched, how reconciliation uses keys, and how that explains most of the bugs you will hit.
