<init>
Adds prefix to external
declarations in a source file.
JavaScript does not have concept of packages (namespaces). They are usually emulated by nested objects.
The compiler turns references to external
declarations either to plain unprefixed names (in case of plain modules)
or to plain imports.
However, if a JavaScript library provides its declarations in packages, you won't be satisfied with this.
You can tell the compiler to generate additional prefix before references to external
declarations using the @JsQualifier(...)
annotation.
Note that a file marked with the @JsQualifier(...)
annotation can't contain non-external
declarations.
Example:
@file:JsQualifier("my.jsPackageName")
package some.kotlinPackage
external fun foo(x: Int)
external fun bar(): String
