I'm not sure if this has been proposed before, if not I would like to propose a native way to handle function composition.
This is not that trivial, it can be achieved via a generic utility however considering this is quite a common pattern it might make sense to include it as a native feature set Something along the lines of Function.prototype.compose(); // chained at end of callstack Function.prototype.composeBefore(); This could* A) *return a new function* B) *chain from the original reference Quite often composition is not limited to a single function so it could be a better approach to allow multiple arguments to be chained Could also follow a similar design as the Java implementation <https://docs.oracle.com/javase/8/docs/api/java/util/function/Function.html#compose-java.util.function.Function-> Regards, Simon Staton
