struct Symbol

• Symbol
• Value
• Object

Overview

A symbol is a constant that is identified by a name without you having to give it a numeric value.

:hello
:welcome
:"123"
:"symbol with spaces"

See Symbol literals in the language reference.

Internally a symbol is represented as an Int32, so it's very efficient.

You can't dynamically create symbols. When you compile your program, each symbol gets assigned a unique number.
