So what's the wait? Let's start!

What is YAML?

Before jumping onto the courses. let's quickly take a look at what YAML is. YAML is a data serialization language that can be read by humans. It's frequently used in configuration files and data storage and transmission applications.

YAML is similar to Extensible Markup Language in that it targets many of the same communications applications, but it has a simpler syntax that is meant to be different from SGML.

Perl, C, XML, HTML, and other programming languages are all represented in YAML. JSON files are acceptable in YAML since it is a superset of JSON.

Nesting is shown in YAML using Python-style indentation. Whitespaces are used instead of tab characters since tab characters are not allowed. Braces, square brackets, closing tags, and quotation marks are not included in the standard style. The extension of YAML files is .yml or .yaml.

A YAML file's structure is either a map or a list.

You may connect key-value pairs with maps. Each key must be distinct, and the sequence is irrelevant. Consider a Python dictionary or a Bash script variable assignment. YAML also allows you to reuse configuration which means you can declare a set of properties as a configuration unit and then refer to that again with declaring them. You can even overwrite them if you want.
