What is DENO?
Why is DENO the future?
It is not always about features when choosing a runtime, sometimes a solution with core mission and sound foundation can be a real game changer.
Web Standards compatibility
Deno focuses on Web Standards compatibility, which means, Deno provides API's using browser standards as much as possible:
Single and Secure Executable
Being able to bundle your application with Deno in a single binary with security flags specified makes distributing your applications extremely flexible for any platform. You can avoid constraints imposed by specific platforms, for example, if deployment platform only supports version x, and you deliver an executable wrapped with your preferred version of Deno, then the platform can't dictate your version.
It's in the box
Deno comes with JSX, TypeScript, REPL, Linting, Formatting, Testing in the box, no need to search for third-party tools and dependencies, these will always be supported.

Decentralized Dependency management
Better dependency management by not having a central point of failure. Deno accomplishes this by using URLs to import modules. A URL can be a reference point to any address on the internet. Using DNS, you can easily have several origins that serve up content. This decentralized model provides redundancy and scalability. URL imports will give your team more confidence that code that is running on their environment is unchanged in production environments, especially with repositories like nest.land.
Nest.Land is a Deno code repository that uses ARWeave Blockchain to store all source code, which means the code is permanent and always available for a minimum of 200 years, but more likely forever. This can give consumers of your modules a great deal of confidence. It is impossible for even the owner of the software to delete from the ARWeave blockchain.
Built to run on the edge
The edge is a server network that distributes executable code to data centers around the world giving everyone with the internet very close proximity to the executable code. This is a perfect solution for web and mobile applications to significantly reduce latency and leverage near-user caching to create incredibly fast experiences for your clients.
Is it right for me?
If you start to feel fatigued by dependency nightmares and growing concerned about security threats via man-in-the-middle attacks or the number of open source libraries you have to trust that lack full support capabilities, then I would recommend looking for a Deno for your next project. Why not take it for a spin in this little getting-started tutorial I created [here https://github.com/twilson63/go.hyper.io].
Cons, why should I hold off on Deno?
People do not like change, sometimes change is hard, too entrenched in one technology and the "features" vs the "pain/risk" don't seem to be enough to invest in a migration. But I think the big one is Meta framework support, Deno does not have a good story for the meta frameworks. I think this will change in 2022, look at Remix, SvelteKit, etc.
