Any idea on what technologies/toolkits are used to build Bloomberg terminal?

  Nowadays the desktop software is built around Chromium. Lots of C++ and one of the largest JS codebases in the world.

    I'd love to know how they make frontends as responsive as possible. To the engineering blog!

    It's not very responsive

    From memory when I worked there 10 years ago, all the Javascript based stuff was pretty slow in a very noticeable way. They've likely gotten better as they are using a well known Javascript and rendering engine, so they're getting many optimizations for free.

    They're very involved in web standards. Rob Palmer from Bloomberg is co-chair of TC39.

    We’re in the middle of TC39 plenary in Tokyo right now as a matter of fact! Rob regularly posts on X as things advance through the staging process, and today is the final day.
