Simple JavaScript Tetris

In plain words

Simple JavaScript Tetris is a web-based implementation of the classic Tetris game built with JavaScript. It's designed for anyone looking to play Tetris directly in their browser without downloads or installations. The game features the traditional gameplay mechanics where players rotate and position falling blocks to complete lines. Being open-source on GitHub, it appeals to both casual players wanting a quick game and developers interested in studying how Tetris is implemented in JavaScript.

  Tetris Built in React to Help You Learn – Tetris on a Plane2017 · ▲12

  I was playing around with a vanilla JavaScript Tetris implementation someone posted, tetris-on-a-plane, learning and recreating it from scratch to sharpen my JavaScript skills. I thought it would also be fun to sharpen up my React skills a little. So I re-implemented Tetris on a Plane in React. I found it really helpful to see a vanilla js app, and then the same thing broken into components and implemented in React, maybe you will too! Regardless, I learned a lot re-implementing it.

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
