This document provides help on getting your macOS development environment up and running with the latest versions of Homebrew, Apache, PHP, etc.
Homebrew is an excellent package manager for macOS; let's install it.

React recently introduced an experimental profiler API. After discussing this API with several teams at Facebook, one common piece of feedback was that the performance information would be more useful if it could be associated with the events that caused the application to render (e.g. button click, XHR response). Tracing these events (or "interactions") would enable more powerful tooling to be built around the timing information, capable of answering questions like "What caused this really slow commit?" or "How long does it typically take for this interaction to update the DOM?".
With version 16.4.3, React added experimental support for this tracing by way of a new NPM package, scheduler. However the public API for this package is not yet finalized and will likely change with upcoming minor releases, so it should be used with caution.
A quick cheatsheet of useful snippet for Flutter
A widget is the basic type of controller in Flutter Material.
There are two type of basic Widget we can extend our classes: StatefulWidget or StatelessWidget.
StatefulWidget are all the widget that interally have a dynamic value that can change during usage. It can receive an input value in the constructor or reference to functions. You need to create two classes like:
Note:
When this guide is more complete, the plan is to move it into Prepack documentation.
For now I put it out as a gist to gather initial feedback.
If you're building JavaScript apps, you might already be familiar with some tools that compile JavaScript code to equivalent JavaScript code:
I bundled these up into groups and wrote some thoughts about why I ask them!

It’s common these day when React & React Native developers use State management library (like Redux). I’ve been using React & React Native for a while now and found out that Pure React is actually not bad. In this article I will share my way of doing things with React & React Native purely, without State management library (represented by Redux).
For those of you who are struggling learning Redux, because of the overwhelming of the whole React/JSX/Babel/Webpack/Native Component/Native Module/.. and have to add Redux to the list just to solve some of React problems, or because of the high learning curve of Redux, I hope you find this article helpful.
Assuming you have some knowledge of React, I will jump right in the problems that most of us encoutered at the beginning of time learning React:
pass data down, pass event up makes us to pass data & function via props and it's hard to manage when amount of props gets huge. (Comunication between component
