Opa is a programming language that is designed to make it easy to develop web applications. It is a compiled, statically typed language that runs on the JVM. Opa is open source and released under the MIT license.
Opa is a very opinionated language. It has a strong focus on simplicity and ease of use. This can be seen in the language's syntax, which is designed to be easy to read and understand. For example, there is no need to use semicolons to terminate statements, and blocks are delimited by indentation.
Opa is also very well suited for web development. It has built-in support for HTML, CSS, and JavaScript. Opa also has a unique approach to database access. Instead of using SQL, Opa has its own query language called QL. QL is designed to be more expressive and easier to use than SQL.
Overall, Opa is a great choice for web development. It is easy to learn and use, and it has excellent tooling and support.
