What are disadvantages of using JavaScript?

1 Answer(s)

We can not treat JavaScript as a full fledged programming language. It lacks the following important features −

  • Client-side JavaScript does not allow the reading or writing of files. This has been kept for security reason.
  • JavaScript can not be used for Networking applications because there is no such support available.
  • JavaScript doesn’t have any multithreading or multiprocess capabilities.
