Node.js

Node.js runs JavaScript outside the browser, which makes it convenient for scrapers, automation scripts and API services written in the same language as the frontend.

Its asynchronous model suits work that is mostly waiting on network responses — fetching many pages or calling many APIs concurrently — which is exactly what most scraping and integration work is.

The npm registry is the largest package ecosystem in existence, with the accompanying caution: dependency count grows quickly and supply-chain risk is real.
