Computed Properties in React

Achieving Computed Properties the right way

React does not have computed properties out of the box like others frameworks do (Ember, Vue, etc.) so, how can we achieve this behaviour the right way ? The most common practice is to "compute" things in the render method if is a class component or just in the body if is a function component.

I am trying to determine if it is possible to build a Swift dynamic library which is itself composed of one of more private modules, without needing to expose to that fact to outside users. My hope was that I could build the private module as a static library, which would be linked into the primary (dynamic) library. The dylib could then be deployed together with its swiftmodule and swiftdoc and be imported, with the private module and its symbols not being exposed at all.

Unfortunately, what I'm currently observing seems to indicate that the private module's swiftmodule also has to be available for the primary library to be successfully imported.

This can be reproduced as follows. I have the following directory structure:

./Greeter/Logger/Logger.swift:

public func log(_ message: String) {

Ideas

I have collected and moderated these ideas from various public sources and put into one place so that problem solvers and solution developers may find inspirations. Because I wish to update it regularly, I have setup as a single page wiki. You may try these ideas on hackathons/competitions/research; some are quite intense problems and some are not. Many of the problems were prepared keeping Dhaka/Bangladesh in mind, but of course can be applied to just about any underdeveloped/developing and sometimes developed countries.
