How widely use is deno?
There’s companies that bet on deno/deno-like runtimes. It’s a move to having more options/control on sandboxing/embedding JS on server runtimes.
Think of how Lua is used. Heavy lifting in a compiled language with Lua on top to cover app specific logic.
Node is in a sense that, but with a stronger emphasis on being a general purpose runtime for JS.
Deno (and similar), gives you more options for embedding and restricting the JS side.
I think it’s worth keeping an eye on, because I think the JS world is soon in an refinement/optimization phase. It’s settling and stabilizing towards a set of core ideas and Deno might be part of that.
