What is your review of Io.js?
How does Io.js compare to other JavaScript runtimes like Deno?
While Deno and Io.js share some similarities, they also have some key differences. For example, Deno uses TypeScript as its primary language, while Io.js and Node.js use JavaScript. Additionally, Deno has a more secure default configuration, as it does not allow file, network, or environment access without prior permission. However, Io.js has a larger ecosystem of packages available via its built-in package manager.
