Getting started

This section reviews how to get started with Golang generics.

• What is a generic?: a quick look at generics in general
• Syntax: how to write generic code
• Constraints: expressing what satisfies a generic type
• The any constraint: the new any keyword
• Composite constraints: elegantly expressing more than one compatible type
• Tilde ~: how to use tilde ~ when expressing constraints
• Type inference: when the compiler figures out intent
• Explicit types: how to explicitly state intent
• Multiple generic types: using more than one generic type
