learnable-opp-solutions-sample

This is a sample solution for some of the tasks

• book.js was demo requested during the Q/A session
• movies.js is a sample solution for movie API/App
• statistics.js is a sample solution for the descriptive statistics system/app

Usage

• clone the repo and cd into the directory such that you are on learnable-opp-solutions-sample
• To run the solution, make sure you have nodejs installed
• use the following command terminal

# run statistics.js
node statistics.js

# run movies.js
node movies.js

• You can change the inputs to see a different output

Sample output

• If the statistics.js is run as it is on this repository, the results look like

➜  learnable-opp-solutions-sample git:(main) ✗ node statistics.js
