Its more deep grained that "the VM is slow" The default python interpreter is really quite fast, but biggest performance problem with python is that everything is an object. Don't believe me? look here: https://jakevdp.github.io/blog/2014/05/09/why-python-is-slow/ https://jakevdp.github.io/blog/2014/05/09/why-python-is-slow... perl is not much older, but in a majority of tasks its faster than python, even c-API python. (it even threads!) Yes it could be engineered around, I assume thats what pypy is doing (although STM is is going to limit performance in a threaded environment) Javascript was designed to be an embedded language, so it was had to be quick to initialize, and have a simple object model. Python was designed to be an easy object oriented language.
