I didn't mean that JavaScript is in the same performance category as Fortran, just that they've both had an above-average amount of investment in performance.
There are certain aspects to FORTRAN that naturally lend it to being fast but you still need to write it in a way that can be optimised, which isn't always the most obvious way. You need to know the language and compiler well to wrote fast code, just as you would with any other language.
