Web Development with ReasonML

It’s Your Turn

Add record types and bindings to the code that analyzes shirt orders as described , to allow it to use Papa Parse. Start with file code/interop/stats/src/Stats.re, which contains comments that tell you what you need to add. Look for sections marked TODO: for instructions. The Error module, which we’ve already developed, is in the file as a guide for the other records you need to create. I’ve taken the shirt-oriented types and separated them into file code/interop/stats/src/Shirt.re to reduce the size of the Stats.re file.

You’ll need to do npm install --save papaparse in the stats directory to run the code:

# presume you are in the stats directory
bsb -make-world
node src/Stats.bs.js orders.csv
