What is the default scope in Node.js application.
(1 Point)
- Public
- Global
- Private
- Local
Solution
The default scope in a Node.js application is Local.
Here's why:
-
When you define a variable in a Node.js module, it is local to that module. This is because each file in Node.js is its own module.
-
Node.js uses the CommonJS module system, and the main concept of this system is that every file is its own module. So, the variables and functions defined in a file are not available to other files unless they are explicitly exported.
-
To make variables and functions available outside of the module where they are defined, you need to add them to
module.exports
. This is how you can create a local scope in Node.js. -
Therefore, unless you explicitly make a variable or function global by attaching it to the
global
object, it remains local to the module where it is defined.
So, the default scope in Node.js is local.
