1.Rust (Deno’s core was written in Rust, Node’s in C++)
1.Any program can write to the filesystem and the network which is a big security concern.
2.In node, the dependencies are stored in node_modules and there is a package.json but the module system isn’t compatible with browsers so our code isn’t fully isomorphic.
2.It has an extensive standard library
3.It has TypeScript at its core.
4.It embraces ES modules.
5.It has no package manager.
6.Security- Deno is secure by default unlike Node.js which has full access to your file system and network.
Ans: You should start with node first then jump to Deno because: Node has been here a while and has matured over the years in terms of compatibility and community, once you get a hands-on Node you can switch to Deno
