Functional programming means programming using functions. See, I need much less than 256 seconds for that! Unfortunately, this definition is as useful as saying that object-oriented programming means programming with objects. So let’s dive deeper. First of all, I mean pure functions as defined by mathematicians. In math, a function always returns the same output for a given input. A length of a string is a function. A form validator is typically a function as well. For the same form inputs it always returns the same result: valid or invalid.

Jest to odcinek podkastu:
Around IT in 256 seconds
Podcast for developers, testers, SREs... and their managers. I explain complex and convoluted technologies in a clear way, avoiding buzzwords and hype. Never longer than 4 minutes and 16 seconds. Because software development does not require hours of lectures, dev advocates' slide decks and hand waving. For those of you, who want to combat FOMO, while brushing your teeth. 256 seconds is plenty of time. If I can't explain something within this time frame, it's either too complex, or I don't understand it myself.
