What issues does Typescript have? not saying it has none, just curious. While much faster than python wouldn't nodejs be a bad option for FB/Instagram too? Why

  IMO Typescript will grow on the backend. It's mainly just not as mature as alternatives and will get better over time. There are small problems similar to python though, like module-level mutable global state. That interferes with certain tools and fast restarts, but can be mitigated the same way as is done in python, ie https://instagram-engineering.com/python-at-scale-strict-modules-c0bb9245c834 https://instagram-engineering.com/python-at-scale-strict-mod... Go is not dynamic enough to build useful abstractions. It does not allow developers to make themselves more productive. It's also more difficult to build hot reloading and high quality reflection based debugging.
