Imagine the state of the world if Brendan Eich had known about Lua and spent those nine days integrating that into Netscape. I believe it had a compatible license, even back in 1995.
Lua is an embedded language and I think most users who want compatibility run or forked Lua 5.1, which is from 2006
It’s not clear to me that Lua in 1995 was better than JavaScript in 1995
