Design Goals

Immutable Data

Mutated data is hard to work with. Use immutable data instead.

Pure Functions

Pure Functions are easy to test and work well with immutable data. They're also referentially transparent and easy for JavaScript engines to optimize.

Single Input

We write functions that take exactly one argument. We curry all functions as needed.

Graceful Fallbacks

Return fallbacks instead of undefined or throwing errors.

Fallback First, Data Last

Passing data as the last argument of a function is great for piping and currying, but TypeScript's typing system works best when we pass in data as the first argument.

We pass fallback values as the first argument and actual data as the last. This helps TypeScript understand the code while still allowing for piping and currying.
