Opa VS Tcl

I remember Opa http://opalang.org/ tried something similar at the time when MongoDB was new and modern. - Source: Hacker News / 8 months ago

We come across some web frameworks and technologies that we think will succeed, but they wither away as time passes by and don't succeed to the level we expected. Which web frameworks and or technologies did you come across that you thought would succeed but did not as per your expectations? For example, I thought that Opa Lang[0] and UrWeb[1] would succeed but did not, even though the ideas were sound. [0]... - Source: Hacker News / 10 months ago

I think the Opa language was doing JSX-like code in the frontend before JSX http://opalang.org/ Both Opa and JSX were created in 2011. Opa had other innovations as well, such having the same code base run on both client and server (like Next.js). Unfortunately it didn't get traction and was abandoned by the creators. - Source: Hacker News / almost 3 years ago

So Lua is the new Tcl. A lightweight scripting language designed to be embedded in other programs. Then I went and looked at http://tcl.tk and it appears the current maintainers of Tcl forgot why it exists as well. ;-) Everyone hated Tcl back in the day for similar reasons. Too lightweight, no serious language features, etc... Maybe we should just use Scheme. - Source: Hacker News / over 1 year ago

Tcl (https://tcl.tk/) is actually pretty good, though I doubt it reaches the speeds Lua can. For modding, it may be enough. Source: over 1 year ago

The main site at https://tcl.tk has lots of resources. Source: almost 2 years ago
