What is YAML?

First of all, let us know what is YAML, When we listen this word many folks will think that this is a programming language stuff, but in reality, It's not a programming language, instead, it's a data format used to exchange data just like JSON and XML are used.

YAML stands for Yet Another Markup Language. But now, we call it YAML Ain't Markup Language.

It is basically a simple human-readable language that can be used to represent data and also used to store some information about configurations.

In YAML we can only store data and not commands.

What is Data Serialisation?

Data serialization is a process of converting these data objects which is a combination of code and data into a stream of bytes that can be used to transfer this data on your physical devices.

We basically use YAML, JSON, and XML for data serialization.

Why YAML is not known as the markup language? Why did its full form got changed?
