@@sanusihassan7125 Depends on all the developers and support currently in place for Node. Just like any technology stack if it ain't broken don't fix it. Unless someone has some time on their hand to make a Node => Deno I don't see it happening overnight.

[@sanusihassan7125]

@@Jessyco you are right

[@pardal_bs]

The only thing I don't like about Deno is how it uses async iterables for listening to connections instead of events. Here's why: 1. It doesn't make sense to "iterate" over a listener. 2. It can cause bugs, because `await`ing inside a `for await ... of` will block requests from coming in. 3. Want to write something after the `for await ... of` loop? It won't execute. It feels like writing in a systems language, where the whole thread stops, waiting for something to happen. I also don't like the callback hell, but sometimes callbacks make more sense.

I think that once you'll understand how servers (especially http servers) work, it'll be easy to switch between every framework, as the hardest part of entering in a new framework is always learning the new syntaxes and what it can do without you needing to configure anything, but then the request respond architecture is always the same across all languages.

Node was released in 2009... over 10 years ago.

The only things that are keeping me on Node are NPM and the popularity of Node.

People might be hesitant to migrate.

[@Soremwar]

The thing is Node is not especial, what gives Node value is the fact that it can run JavaScript, meaning that most of the code already written in Node can be ported to Deno, so it's not like Deno begins at 0% percent, it can inherit everything Node already has For example, I can use React directly on my Deno app without having to rewrite a single line of it

I think the way that these new languages will become popular is for Senior devs looking to use something new at their companies start using a combination of Svelte and Deno.

[@Geomaverick124]

I think that it will become one of the big programming frameworks / languages but wont overtake Node...Similar to how typescript wont overtake javascript or Svelte over the other frameworks... at least for a few years. On the front we will have React, Angular, Vue, Svelte...and on the backend will have Node/Express, Deno, Python,Php/Laravel, and C# as choices for the most popular
