I Built Tetris in 150 Lines of JavaScript — 7 Pieces, Rotation, Line Clear
Tech Daily Byte Analysis

The fact that this Tetris game can be created in such a short amount of code underscores the rapid progress of web development, where complex tasks are becoming increasingly manageable with fewer lines of code. This development is part of a broader trend where web developers are pushing the boundaries of what is possible on the web, extending the traditional roles of web development beyond mere user interface and into areas like game development, data analysis, and more.

As game development on the web continues to gain traction, we can expect to see more innovative applications of web technologies, blurring the lines between web and native applications. This trend may also lead to a shift in how game development is perceived, with web development becoming a viable option for small-scale game development projects.

About the Source

The whole game is a 2D grid + 7 tetromino shapes + collision check + matrix rotation + line clear scan. Same game loop pattern as Snake and Pong, more state.
