No mention of Ejacs‽

At 17 years old, I think it's comfortably outside of the scope of the article I was focusing on (the last decade), but thanks for bringing it to my attention!

> Ejacs is based heavily on work by Brendan Eich (SpiderMonkey, Narcissus) and Norris Boyd (Mozilla Rhino).

I did mention all of these, at least!
