Lambda abstraction

Lambda abstraction is when you take a group of things and give them a nickname. It's kind of like calling your dog "Fido" instead of always saying "my furry, four-legged friend with floppy ears and a wagging tail".

In computer programming, lambda abstraction is used to make code simpler and easier to understand. You can take a bunch of lines of code that do a specific task and give them a simple name or "nickname" using lambda abstraction. This makes it easier to reference that bunch of code later on without having to write out all of the lines each time.

Think of it like this: if you want to tell someone to go get a glass of water, you could say "walk over to the kitchen, open the cupboard, take out a glass, turn on the tap, hold the glass under the tap, wait until it's full, turn off the tap, and walk back over here with the glass". Or you could just say "go get some water". That's kind of what lambda abstraction does – it simplifies lines of code into a shorter name or phrase that can be easily remembered and used as needed.
