In code like 'a?.b == 42', we can immediately generate equality comparison result when receiver is null (false for '==', true for '!='), since the primitive value is definitely non-null. Otherwise unnecessary boxing/unboxing is generated to handle possibly null result of 'a?.b'.
JavaScript Translation
This module performs the translation of Kotlin source code to JavaScript.
There are various Kotlin APIs to JavaScript environments and libraries in the js.libraries project.
Compiling the Kotlin Standard Library for JavaScript
The Kotlin Standard Library for JS is built with gradle, see the corresponding module's ReadMe.
Reusing JVM based test cases in JavaScript
Any Kotlin test cases using the org.junit.Test annotation and the kotlin.test package, such as this test case are automatically converted to JavaScript using QUnit.
This allows the test cases to be run directly in a web page in any web browser.
Using the Kotlin Library in JavaScript
There is a simple sample which shows how to use the Kotlin Standard Library from inside JavaScript in a web page.
