JS++ 0.5.1: ‘foreach’

We just released JS++ 0.5.1, which features the foreach keyword.

Basic usage is as follows:

external console;

int[] arr = [ 50, 40, 30 ];

foreach (int value in arr) {

// Output:
// 50
// 40
// 30

More complex usage, such as arrays of objects, are also possible:

external console;

class Foo
	string bar() {
		return "bar";

Foo[] foo = [ new Foo(), new Foo(), new Foo() ];

foreach (Foo value in foo) {

// Output:
// "bar"
// "bar"
// "bar"

Additionally, the for-in keyword has been implemented. It is a counterpart to the foreach keyword in the sense that it enumerates keys rather than values.

JS++ 0.5.0: Basic Classes

JS++ now supports the ‘class’ keyword. As promised, we would have classes available by Q1 2017. Notably, we are providing “basic” classes, so the following features are supported:

  • ‘class’ keyword
  • Inheritance
  • Constructors (including private/protected constructors that limit instantiation/inheritance)
  • Static Constructors
  • Instantiation
  • Fields
  • Methods
  • ‘this’ keyword
  • ‘super’ keyword
  • Method Overloading
  • Constructor Overloading
  • Getters and Setters (via ‘property’ keyword)
  • Type system support
  • Debugger support for classes (via source maps)

What did we consider to be outside the scope of basic classes? The following features are currently not available yet:

As an example of what you can do with JS++ classes, we included an example with the Tiled Map Editor:

Tiled Map Editor

The included sample for Tiled can be found in the ‘Samples/Classes/tiled-loader’ directory with JS++ 0.5.0. Currently, it will load all maps exported to JSON with orthogonal tiles. It’s just a small but powerful example of what you can start doing with JS++ for early adopters.

I am also happy to inform that the backend for the JS++ website is written completely in JS++, and it has now run stable for one week without a single crash or error (other than 404 errors).

Finally, we have made the decision to not include the Mac/Linux installer… yet.

Be sure to check out the documentation on the ‘class’ keyword to get up to speed on JS++ classes.

Website Backend Now Powered by JS++

As of 8 March 2017, the backend for the JS++ website is powered by the JS++ programming language itself (in conjunction with Node.js). The backend is developed using JS++ with classes, which will be available in the next release.

We wanted to wait at least 24 hours to ensure stable operations before making this post. Based on our logs, it is clear everything is running smoothly.

Our website frontend is not completely written in JS++. It will likely be migrated in the future if the code becomes more complex.
