JavaScript from 2001 on India's largest private bank site

Strings are immutable, so each one of these concatenations creates a new string with slightly more content.

I have seen modern JavaScript that can be just as bad as this.

Most modern JavaScript I've seen is worse than this.

At least it's not a minified blob built up from dozens of repos whose primary purpose is to make its authors look (feel) productive/prolific.

Not really correct for JavaScript (among others). All modern implementations optimize repeated appends in cases like this. They all have ropes, too.
