Why are the installation packages in java, haskell, python, and erlangwin large, with dozens or even hundreds of megabytes while node. js is small and only a few megabytes?

0. Reply content: If you use Node. js, can you use it if you don't need npm to pull dozens of hundreds of megabytes of data? The python installation package looks like a dozen mb. It was just yesterday that node was used. During the installation, it was only 5 MB in size and thought it was lightweight.
When you started writing code, didn't you always download various packages from npm?
In a project, there are more than 10 MB of npm packages, not a small node, but the library you need will be downloaded only when there is demand from npm, maybe that's why so many people like him.
