    Handle Errors in Ramda Pipelines with tryCatch

    ramdaRamda

    Handling your logic with composable functions makes your code declarative, leading to code that's easy to read and easy to test. Breaking that up to wrap some risky function in a try/catch block introduces imperative code and makes it harder to maintain that declarative approach. With Ramda's tryCatch function, you can handle errors right in the middle of a composition and leave your code clean and functional. We'll also see how you can use propOr to avoid common "cannot find X of undefined" errors.
