Thank You, Deno

Deno is joining Cloudflare and winding down its runtime after failing to achieve critical mass against Node.js dominance. However, the project successfully pressured the Node.js ecosystem to adopt many of Deno's original innovations—including better permissions, TypeScript support, and web-standard APIs—even though these improvements came through Node itself rather than Deno. Deno's legacy demonstrates the importance of competition in driving ecosystem improvements, despite the alternative runtime experiment ultimately not displacing the incumbent.
