In the question“What are the best languages that compile to JavaScript? ” Java (via GWT) is ranked 21st while Mint is ranked 44th. The most important reason people chose Java (via GWT) is:
That's Java, so it is strongly typed, and we can use fully the IDE: error detection, refactoring, auto-completion, etc.
Specs
Question Ranking
Pros
Pro Strongly typed, good tooling
That's Java, so it is strongly typed, and we can use fully the IDE: error detection, refactoring, auto-completion, etc.
Pro Familiar for Java developers
Perfect if you have a strong background in Java programming, and need to code for the client side.
Pro Fantastic IDEs
Because Java is statically typed, integrated development environments (IDEs) for Java can provide a lot more feedback on errors you will encounter. Java IDEs can give you specific errors in the location where they occur without having to run the code every time. This makes is faster to debug and learn from your mistakes.
IDEs also have extensive auto complete capabilities that can help you learn the programming libraries you are using faster and tell you what functions are available.
Pro Most commonly used language in industry
Java is one of the most popular languages in industry, consistently ranking either first, or occasionally second (behind C or Javascript) in terms of usage. Polls (see sources below) show it to be consistently in high demand, particularly as measured by job board postings. This makes Java a great time investment, as you will be easily able to get a job utilizing your skills, particularly as those Java applications in production now will continue to need maintenance in the future. It also results in great support for tools and plenty of computer science books, example projects and online tutorials.
Pro Consistent programming standards
Most Java code follows very standardized coding styles. This means that when you're starting out, there are fewer questions about how you should implement something as the programming styles and patterns are well established and consistent. This consistent style means that it's often easier to follow others' example code, and that it's more likely to meet at least a certain minimum standard of quality. This discipline with consistent stylistic standards also becomes useful later, when collaborating on projects with larger teams.
Pro Highly optimized JavaScript
Produced JS is highly optimized, can be separated in modules with lazy loading, can be internationalized while loading only the chosen language.
Pro Writen in Crystal (Language)
Crystal is one of the best and elegant languages.
Pro Constructs for synchronous and asynchronous computations
Pro Easy to learn and write
Everything is an expression.
Pro HTML and CSS integration
HTML can be written with minimal differences.
Scoped .CSS can be written for elements in components.
Pro Good error support
200+ unique error messages to help you on the way.
Pro Everything is typed
Everything is typed using a simple type system
Pro Dead code elimination
Only used parts of the code compiles into the final bundle.
Pro Built-in formatter
Mint has a built-in formatter to format your code, it can run standalone or with the development server.
Pro Batteries included
Mint contains everything you need to build the frontend of web applications from styling to data storage through HTTP requests to testing.
Pro Integrated testing
Testing is part of the language and there is a test runner built in which runs tests in the browser.
Cons
Con Too verbose
- A Hello world needs package, class, static method and the actual
printf. - Reading a line from input requires instatiating 5 objects in the right order.
- Exceptions are everywhere, particularly since all values are nullable.
- Java has a getter/setter culture, but without native syntax support.
- portable Java code lacks anonymous functions, and continues to lack good support for partial application, compensating instead with verbose design patterns, kludges like anonymous inner classes, or just inline code.
- It is statically typed without type inference, with a culture that promotes long class names.
- Poor support for sum-types and pattern matching leads to overuse of inheritance for dynamic dispatch and chains of nested conditionals
Especially for beginners, this can make reading Java code feel overwhelming; most Java courses tell students to simply copy, paste, and ignore a significant percentage of the code until they've learned enough to understand what it means.
For experienced programmers, this makes Java feel tedious, especially without an IDE, and actively discourages some solutions and some forms of abstraction.
