Node.JS callbacks - question 1: I have 2 files (1) decon_t2_calledFile.js and (2) decon_t2_callingFile.js. My aim is to take the string output of file 1 (decon_t2_calledFile.js) and access through file 2 (decon_t2_callingFile.js))
module.exports = function(callback){
function () {
// Contents of this anonymous function will serve as output
// from this file
console.log('** Output from decon_t2_calledFile.js ** ');
}
};
