> - Also, as Sam points out, full-stack devs can ship quickly using TS for both backend and frontend.
Typescript (which is still "Javascript") is extremely immature for a "backend" language.
I can't take anyone seriously if they believe or use such a pseudo-typed language like typescript and especially a weakly typed language with dynamic types on a costly runtime such as Javascript on the backend.
Both of them should stay far away from anything backend.
Yeah I'd use something different for sure. If bang per buck is needed. Since an API call to AI can cost like 1c or more maybe it doesn't matter if you waste 100ms of cpu time.
This is why TS is winning. Agent frameworks largely replace backend logic, and they have their own quirks with runtime costs. Most agent use cases look like chron job scripting or chatbots right now, and I expect we'll see far more use cases with proactive scripts. All of these avoid traditional bottleneck of runtime because the AI is the bottleneck.
There is value in fast iteration and delivery. These are early stage startups, the clock is ticking. I wouldn’t do it with JS but I understand why it would be used.
Now we can argue how good or bad the nodejs (or any alternative JS implementation) is. At the end of the day the objective is most likely to rock the boat enough to be acquired and have a payday. With enough discipline you can get far before the footguns show up.
It depends. There is no right or wrong.
