While it doesn't have the batteries, typescript's gradual typing is much nicer than python's, so for some use cases it's a better language. All languages come with tradeoffs in terms of performance, development/maintenance cost and ease of hiring. Most businesses only care superficially about performance, which leaves developer productivity and ease of hiring. Node/typescript isn't terrible in terms of developer productivity, and it's got the best hiring story of any language. Python is good in both those ways too, but since you already need a javascript hiring pipeline for the client it's easier just to use node and hire full stack devs.
