Clojure vs JavaScript vs PHP: What are the differences?
# Introduction
1. **Syntax**: Clojure is a LISP dialect with a focus on simplicity, immutability, and functional programming paradigms, while JavaScript and PHP are both imperative languages with C-style syntax.
2. **Data Structures**: Clojure emphasizes immutable data structures, while JavaScript and PHP primarily use mutable data structures.
3. **Concurrency**: Clojure has built-in support for state management and mutable data structures for concurrency, whereas JavaScript and PHP rely on libraries or tools for managing shared state and concurrency.
4. **Tooling**: Clojure has a strong emphasis on REPL-driven development and interactive programming, while JavaScript and PHP have more traditional development workflows with separate compilation and running steps.
5. **Libraries and Ecosystem**: Clojure's ecosystem is more focused on functional programming and immutable data structures, while JavaScript and PHP have a broader range of libraries and frameworks catering to different development needs.
6. **Performance**: Clojure, being a compiled language running on the JVM, typically has better performance compared to JavaScript and PHP, which are typically interpreted or run on top of a runtime environment.
# Summary
In Summary, Clojure differs from JavaScript and PHP in its syntax, emphasis on immutable data structures, concurrency support, development tooling, ecosystem focus, and performance characteristics.
