I have a project using node.js. It's my first time using nodejs and I want to export an array to my app. Here is some code:

module.exports = { 

    var arrays = [];

    arrays[0] = 'array 0';

    arrays[1] = 'array 1';

    arrays[2] = 'array 2';

    arrays[3] = 'array 3';

    arrays[4] = 'array 4';

    var r_array = arrays[Math.floor(Math.random() * arrays.length)].toString();

}

At the end I want to use the var r_array in my app.js but I don't know how.

You'd want to define a function which returns the randomized portion of the array:

module.exports = {

  getRArray: function() {

    var arrays = [];

    arrays[0] = 'array 0';

    arrays[1] = 'array 1';

    arrays[2] = 'array 2';

    arrays[3] = 'array 3';

    arrays[4] = 'array 4';

    return arrays[Math.floor(Math.random()*arrays.length)];

  }

};

Also you should embed the array into the function so it actually returns something.
