Thanks for js-ifying this!

The previous code also replaced spaces with underscores. Not sure if this is still desired but I at least wanted to point it out :)

Jup this is on purpose. The space search is now covered by line 252 if (lint.id.indexOf(therms[index]) !== -1) this allows the words to be out of order which is likely when somebody just types them in. It could also reduce performance since we are not using a regex in the replace function, but I'm not sure about that :)

Ah of course, that makes sense!

(I would expect any decent JS enngine to optimize the simple regex to a byte match so it's probably as fast as the literal replace.)

// The use of `for`-loops instead of `foreach` enables us to return early
