%GetOptimizationStatus return a set of bitwise flags instead of a single value, to access the value, you need to take the binary representation of the returned value. Now, for example, if 65 is returned, the binary representation is the following:

(65).toString(2).padStart(12, '0');
// 000001000001

Each binary digit acts as a boolean with the following meaning:

/*
 Let's Assume we want to have a Functor which creates a new Module from
 a specific Component Model
 
 The Functor recieves another Module named `Component`, which needs to satisfy certain constraints:
 - Component requires an abstract type t (no matter what concrete type)
 - It also needs to implement a `render` function which gets said type t and returns a `string`
 
 Also, the newly created module will then contain a function `doSomething`, which will handle any
 instance of `Component.t`. So our `Component` also will need a function to create an instance for that,

Async/Await - The challenges besides syntax - Cancellation

This is the second article in a series of articles around Rusts new async/await feature. The first article about interfaces can be found here.

In this part of the series we want to a look at a mechanism which behaves very different in Rust than in all other languages which feature async/await support. This mechanism is Cancellation.

Async/Await - The challenges besides syntax

4 years after after the release of Rust 1.0, it seems like Rust is now finally getting close to getting support for async/await - a language feature which aims to make it easier to write programs in an asynchronous fashion (where multiple logical tasks get multiplexed on a lower number of OS threads).

One of the last steps before the feature is stabilized is choosing the best possible syntax. The discussions around syntax have triggered an enormous

~80b ponyfill for String.prototype.replaceAll() with good performance.

Why ponyfill? Because this is a proposal for a spec, and polyfilling it in-place before it gets solidified could break code that relies on an incorrect implementation.

Usage example:

Getting Started With Plug'n'Play

If you use create-react-app, #5136 (released with the 2.0) implements a --use-pnp option that allows you to easily create a new project using PnP! In this case, just use create-react-app --use-pnp together with Yarn 1.12, and you're good to go! 👍

Plug'n'Play is a new initiative from Yarn that aims to remove the need for node_modules. It's already available, and has proved being effective even on large-scale infrastructures. This document describes in a few steps how to quickly get started with it. Spoiler alert: it's quite easy 🙂

First, download a package manager that supports it. Yarn 1.12 already does, so that's what we're going to use! To install it, just follow the instructions on our website: https://yarnpkg.com/en/docs/install

If everything is ok, running yarn --version should give you v1.12.1 or higher. If you don't get this result maybe a
