I think a bigger reason is that Python prioritizes simplicity of internal implementation. To be sure, the internal implementation of CPython (the only one I'm familiar with) is complicated as hell. But it's a whole lot simpler than any fast JavaScript runtime I've ever used. I think that's the result of a conscious choice by the maintainers/BDFL/community in Python, not a side effect of it having less funding (assuming that's the case).
