- The biggest weakness of Node.js is its single-threaded event loop. This suggests that Node.js can just process one request at a time. If more requests come in, they are placed in a queue and managed in the order they were received. This can result in bottlenecks and slowdowns if the application is not designed correctly.
- Node.js has poor library support when compared to languages such as Java or Python.

This can bring about compatibility issues and security risks if the libraries are not appropriately maintained.
- Node.js does not have integrated data security features such as encryption, authentication, and authorization. Developers have to develop their own security measures to secure their data. This can be
