The **`export` statement** is used in [Javascript](https://www.educative.io/answers/javascript-style-guide) modules to export functions, objects, or primitive values from one module so that they can be used in other programs (using the 'import' statement).

> A **module** encapsulates related code into a single unit of code. All functions related to a single module are contained in a file. 

**Module exports** are the instructions that tell [Node.js](https://www.educative.io/blog/what-is-nodejs) which bits of code (functions, objects, strings, etc.) to `export` from a given file so that other files are allowed to access the exported code.




# Syntax
The following code exposes a function to be exported in the file `Log.js`.
```node.js
module.exports = function (msg) { 
    console.log(msg);
};
```
We can now use the above module as shown below.
```node.js
var msg = require('./Log.js');

msg('Hello World');
```

# Code
The following code declares and exports a list (`myNumbers`) and a function (`myLogger()`) in the file `modules.js`. We then import these modules into our main file (`index.js`), which allows us to call these functions there.


export const myNumbers = [1, 2, 3, 4];
const animals = ['Panda', 'Bear', 'Eagle']; // Not available directly outside the module

export function myLogger() {
  console.log(myNumbers, animals);
}

const functions = require('./modules');
let { myLogger, myNumbers } = functions

console.log("Calling myLogger function:")
myLogger();
console.log("\n Printing myNumbers list:")
console.log(myNumbers);
