This repository contains NodeJS exercises made in the Skylab Coders Academy Full Stack Web Development Bootcamp.
Create a app.js that require another file called calculator.js When we call node app.js we should show in the console the following:
The sum of 3 & 7 is: 10 The multiplication of 3 & 7 is: 21
app.js should only show in the console the result of calling the functions sum & multiplication
These methods should be defined (and exported) in calculator.js
Create a folder called operations and create in every folder a file exporting every operation needed in the main app.js file
app.js operations/ sum.js multiplication.js substraction.js division.js
Install the module moment and use it to show the current time in this way:
