CFML (ColdFusion Markup Language) is an open source and commercial (JIT) compiled dynamic and loosely typed JVM scripting language that embodies classic OO, and functional programming, making it easy to learn, fun to use. CFML brings the power and scalability of the J2EE ecosystem but without the boilerplate of Java.

About CFML

component {

  // helloWorld greets the world.
  function helloWorld() {
    return 'Hello, World!';


ColdFusion (CFML) is a JVM scripting language whose syntax is similar to C or JavaScript. It JIT compiles to byte code that runs on the JVM but is dynamic and loosely typed, making it fast and easy to develop in. CF is a multi-paradigmed language, supporting classical OO and functional programming.

CFML also has a built-in tag-based templating language that makes it ideal for web apps. It runs in a J2EE container with many bundled libraries that make it very productive without the need to install many packages. CFML has native support for zip files, PDF and Excel generation, E-mails, FTP, HTTP, S3 file systems, ESAPI security libraries, JDBC drivers, JSON and REST APIs.

CFML can also leverage any Java project by dropping the jars in project and directly instantiating Java objects in your code. You can learn more about basic syntax and first class data types in this guide: Modern ColdFusion (CFML) in 100 Minutes

Exercism is a great website

The reviews are incredibly helpful because they help me see things that I missed, learn about new ways and sometimes interesting discussions that can add a fun twist to maybe a simple problem.

Relaxed. Encouraging. Supportive.

After studying English, I took the road less traveled, which somehow led me to become a developer. Perhaps because code can be poetry and applications are the built on creativity, logic, and language, I've continued exploring and haven't looked back.

As a developer I never want to stand still. Always improving on my syntax, performance, and knowledge. Currently finishing up my Masters degree in Computer Science but want to also help others grow.
Fun. Challenging. Interesting
