🧠 adobe rule evaluator

During an interview with Adobe, I was asked to express logical statements as objects, and create a function that evaluated them against a set of data. Modeling the objects was tough, but after that everything else fell into place!

❓ question

You've most likely written logical statements in code before, like the one shown below.

month === "August" && (day > 15 || [1, 5, 9].include(hour))

Now imagine you are implementing a rule builder that allows the user to create logical statements. Model the logical statements as objects, and then create a function that evaluates them against a set of data.

🤔 assumptions

I made a few basic assumptions to bound the complexity of the problem.

First, I decided to limit my support to the following logical operators.

• and
• or

Additionally, I decided to support only the following comparison operators.

• eq
• neq
• gt
• lt
• gte
• lte
• inc
• ninc

And finally, I limited the input data types to string, number, and boolean.
