First of all we will need to npm install. Libraries can´t be used in the exercise, but we only have linters. Index.js is the file where we have to develop our exercise. Pressing f5 we can launch node server. Input files should be stored in input folder. Output files will be stored in output folder. src contains other exercises tried, with their corresponding index.js, inputs and outputs.
