What is a Function and How To Create and Use a Function - Learn How to Program for Beginners #3

Functions in computer programming help you to break down your programs into smaller pieces that perform specific actions. Functions usually take an input and return some sort of an output. Functions are some of the most important building blocks in all of programming, because it provides order and structure to your programs and communicates to other developers how the code should
actually work just by taking a look at it.

When I person randomly comes across your video (I'm talking about beginners), it is unclear what programming language is being discussed. I think it makes sense to mention the name of the language in the title.
In the same time, the way you present and speak is just cool. For me personally it's really pleasant to listen.
Keep on developing your channel and be flexible enough to vary the style of videos until you find the format that fits best.
Good luck!
