An opinionated list of excellent Clojure learning materials

These resources (articles, books, and videos) are useful when you're starting to learn the language, or when you're learning a specific part of the language. This an opinionated list, no doubt. I've compiled this list from writing and teaching Clojure over the last 10 years.

Getting Started with Clojure on Windows

Clojure is an amazingly powerful language. Using it (and watching Rich Hickey videos) has changed the way I think about programming, and the way I code in general. Once I learned the basics of the language, which was a relatively quick process, I fell in love and couldn't look back. I hope this post can help others who are new to Clojure get up and running quickly and painlessly.

This post is opinionated in the sense that I'll suggest certain tools to help those who are new to this scene get on their feet. The things you'll need are:

• Leiningen (pronounced LINE-ing-en) - This is like a package manager, build tool, task manager, and more in one tool. Think npm or nuget, but with more capabilities. There is at least one other build tool for Clojure (boot), but Leiningen is the most widely used.
• JDK - Clojure runs on Java. Throw out any qualms you may have about Java, we aren't coding in Java (though we can through Clojure, and sometimes tha

How to Install Homebrew on Manjaro

Steps

1. Install base-devel

    pacman -Syu # CAUTION: this updates the whole system
    pacman -S base-devel
   

2. Run the installer script

public static T Time<T>(string op, Func<T> f)
{
  var sw = Stopwatch.StartNew();
  T result = f();
  sw.Stop();
  Console.WriteLine($"{op} took {sw.ElapsedMilliseconds} ms");
  return result;
}

Comparison of npm scripts vs Gulp

npm scripts

Pros

• npm scripts are low-level and leverage the actual library you want to use (example: "lint": "eslint ./")
• package.json is a central place to see what scripts are available (also npm run will list all scripts)
• When things get too complicated you can always defer to another file (example: "complex-script": "babel-node tools/complex-script.js")
• npm scripts are more powerful than one might first think (pre/post hooks, passing arguments, config variables, chaining, piping, etc...)
