Lambdas handlers can be invoked with many different, but always complex, event arguments. Add to that the context, callback, matching return type and you basically start listing all the different ways that your function can fail in production.

From time to time I still see a for loop in JavaScript codebases. Linters are frequently angry about them. Let's see how we can replace them.

A discussion about issues we've stumbled upon and a solution that simplified our CDK workflow.

Introducing useComplexState hook, - a small wrapper combining Redux Toolkit, useReducer with some extra syntax sugar to make things even simpler and more to-the-point.

A few patterns to help you deal with randomness in your codebase.

What do you do when you are in need to figure out a complex type? Many just give up - they either make a use of any or jump through a lot of hoops that in the end makes their code less maintainable.. but at least they didn't have to figure out the types, right? :)
