Function 'kotlin.js.js' is to be redesigned in JS IR backend, partially because it is a hard feature to support. Current implementation is unstable and can cause problems around inlining and name generator. Luckily most of its use-cases can be covered by simpler features like dynamic expressions and external declarations. Thus we are reducing it's usage in stdlib to make IR backend more stable in current state. JavaScript features that can't be covered by dynamic expression are implemented in 'jsOperators.kt' file respectively for each backend: - 'internal inline' function which calls 'js' function inside for current pre-IR backend - 'internal' function with '_hack' parameters for JS IR backend which will be later intinsicified in a compiler
