String::toByteArray() does not compile in Kotlin [js]

Question

The following code does not compile in Kotlin Js:

"My String".toByteArray()

Any ideas why?

The error returned is:

[INFO]
[INFO] --- kotlin-maven-plugin:1.1.51:js (compile-js) @ client ---
[INFO] Kotlin version 1.1.51 (JRE 1.8.0_144-b01)

The same code compiles in the non-javascript Kotlin compilation:

`String.toByteArray()` is from `kotlin-stdlib`/`kotlin-text`. Have a included a reference on that? According to this page: https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.text/to-byte-array.html — cramopy, Oct 21 '17 at 11:37

String.toByteArray function is not provided in the Kotlin/JS standard library.

The documentation of that function has a section about Platform and version requirements. JVM there means that it's only available on Kotlin/JVM.

Is there a reason why isn't it available on every platform? – Yoav Sternberg Oct 21 '17 at 15:10
