2
Callback Hell
Overusing callbacks can lead to complex, nested
code that is difficult to understand and
maintain.
3
Memory Leaks
Node.js applications can easily develop memory
leaks if objects are not properly managed and
cleaned up.
4
Blocking the Event Loop
Synchronous code can block the event loop and
cause performance issues, so it's important to
use asynchronous code where appropriate.
5
Exception Handling
Improper exception handling can cause an
application to crash, so it's important to
catch exceptions and handle them appropriately.
6
Callback Errors
Neglecting to handle errors in callbacks can
cause unexpected behavior and lead to bugs.
7
Global Variables
Overusing global variables can lead to variable
collisions and unexpected behavior.
8
Modules and Package Management
Neglecting to properly manage dependencies and
modules can lead to version conflicts and other
issues.
9
Security

• Neglecting security best practices can leave an
  application vulnerable to attacks, so it's
  important to be mindful of security concerns
  when coding in Node.js.
