Syntax Reference

Use this section when you are reading Clojure code and feel “stuck on the shape.” It’s a compact reminder of how forms are written and what common literals mean.

For Java developers, the goal is fluency: recognize the few special forms, understand namespacing and require, and get comfortable with Clojure’s data literal syntax so you can debug by inspection.

In this section

• Basic Syntax and Data Types
  How to read Clojure forms and the literals you’ll see most: numbers, strings, keywords, symbols, and nil.
• Collection Literals
  Quick reference for Clojure collection literals and the operations you’ll use most on lists, vectors, maps, and sets.
• Functions and Anonymous Functions
  How to define and use functions in Clojure: arities, anonymous functions, variadic args, destructuring, and apply.
• Special Forms and Macros
  Recognize the small set of special forms and understand what macros do when reading real Clojure code.
• Namespaces and Imports
  How to declare a namespace, require Clojure libraries, and import Java classes in an idiomatic ns form.
