Can JavaScript be used to read and write to a file?

Question

.js file operations

Answer 1

It can be. But it's not design for that, so it's often a little difficult and limited... if you think JS in browser ( for security reasons, a script wouldn't normally access to the user's files system -- but if you are the user, you may succeed in cicumventing ).
If you are thinking to NodeJS, it's more made for, but it means installing a server.

Searches on google would bring you many examples ^^

Answer 2
