Error Handling Strategies

Introduction

There are various ways of handling errors in programming. This includes not handling it. Many languages have created more modern ways of error handling. An error is when the program, intentionally, but mostly not, breaks. Below, I’ll cover the 4 main ones I know: try/catch, explicit returns, either, and supervising crashes. We’ll compare various languages on how they approach errors: Python, JavaScript, Lua, Go, Scala, Akka, and Elixir. Once you understand how the newer ways work, hopefully this will encourage you to abandon using potentially program crashing errors via the dated throw/raise in your programs.

Functional Programming for OOP Developers: Part 2 – No Errors and Getting Things

Introduction

In my journey to learn functional programming and drink deep of the kool-aid, I wanted to share my latest learnings. Specifically around the quest for no errors and how you get things.

I’ve also just recently applied these same concepts in Python, not just JavaScript, so I’ll mix and match the examples to show how the concepts are universal.

After reading this article, you should understand why errors aren’t helpful embedded in your code & avoiding them is good and why we use functions to get things instead of the old way of assigning variables. Check out the first article if you missed it.
