Delegated property names in javascript code

I have a delegated property name in kotlin code. In compiled javascript code, it is transformed into an object property name_pw16at$_0. My experiments show that this suffix is independent of the type of delegate and the actual type of property. In the official documentation describes how delegated properties are represented in jvm classes: with the suffix $delegate added to the real name of property, but there is no information about javascript case. So, can i find out, which algorithm is used to generate this suffix in javascript compiled code?
