If you go to
https://docs.ruby-lang.org/en/2.6.0/syntax_rdoc.html
or
https://www.ruby-lang.org/en/documentation/
"The official Ruby API documentation"
https://docs.ruby-lang.org/en/
https://docs.ruby-lang.org/en/2.6.0/
then under 'pages' choose 'syntax'
Then you get this page, with its links to other relevant pages
https://docs.ruby-lang.org/en/2.6.0/syntax_rdoc.html
The Ruby syntax is large and is split up into the following sections:
Literals
Numbers, Strings, Arrays, Hashes, etc.
Assignment Assignment and variables
Control Expressions
if, unless, while, until, for, break, next, redo
Methods
Method and method argument syntax

Modules and Classes

Exceptions
