Why do we use N-API in Node.js?
The idea behind n-api is to build a stable interface on top of the V8 APIs that you write your native modules against. This approach introduces a series of benefits: Remove the need to recompile modules, as the interface never breaks (think of it as syscalls but for Node.js).
What kind of architecture does Node.js have?
