Finished reading of #exploringes6 The first step of 2019 ✔️ Really good book, advanced and explains a lot what happens under the hood as examples of use cases. #javascript.

This book is an excellent addition to #ExploringES6 and looks like several additional chapters to it. Also, I've got a feeling that I've seen some improvements in the book format, but I don't remember them.😊

It looks like #ExploringES2016AndES2017 is much shorter than #ExploringES6.🤔 I'm relatively new on Earth and still need to learn to compare. #ES2017

This one is interesting, and I've already mentioned it in the context of the #ExploringES6 book. New #JavaScript modules support cyclical dependencies and thus allow violating this principle. This example is a good illustration of the uncertainty of programming knowledge.

After a long vacation its time to get back to reading!☺️🎉 I've finished #ExploringES6 now its time to change my pinned tweet to a new one.

Yesterday I finished #ExploringES6. That was a long journey, I've started a book in April. The book explores #JavaScript deeply, describes a lot of inevident nuances. Guess, @rauschma started writing it in the 1870s, the result is tremendous. #ES6

After all chapters of #ExploringES6, there is an overview of the discussed themes. I find it useful because of already forgetting some parts.😊

Due to the way floating numbers are represented in a computer, you should not compare them using equality check in #JavaScript. For these purposes use Number.EPSILON from #ES2015: 0.3 - (0.1 + 0.2) < Number.EPSILON. #ExploringES6 #ES6

Reading about combination of property descriptors and proxies in #JavaScript is 🧐🤔🤔🧐🤔🧐🤔🧐🙈🧐🧐🧐 #ExploringES6 #ES2015 #ES6

Have you ever used the defineProperty method in #JavaScript? It allows configuring a property. I can't imagine a lot of use cases for it except forcing a particular way of programming. But when you have to force it programmatically haven't the things gone wrong?🤔 #ExploringES6

Reading section "28.5.4.3.1 Use cases for invoke" in #ExploringES6 indeed makes me think that things are covered deeply in this book.😆 #ES2015

If you ever wondered which use cases do proxies in #JavaScript have, here is a good example: Proxies are ideally suited for implementing revocable references because they can intercept and forward operations. #ES2015 #ExploringES6

Using proxies, you can allow negative indices for the arrays in #JavaScript. E.g., arr[-1] will return last value. Here is the link to learn more: exploringjs.com/es6/ch_proxies…. #ES2015 #ExploringES6

On Monday #ExploringES6 touched upon the subject of metaprogramming and today #DesignIt introduces metamodeling. Metamodel defines the concepts used in a model and the rules for how those concepts are applied. #SoftwareArchitecture #DesignThinking

Proxies can be used as prototypes in #JavaScript. You can redefine default behavior for getting non-existent values. Do not know if this is a good practice🤔 #ES2015 #ExploringES6

Even more, revocable proxies exist in #JavaScript. That means that you want to cancel any further interception. const {proxy, revoke} = Proxy.revocable(target, handler); #ES2015 #ExploringES6

Guess I've forgotten to describe what proxies in #JavaScript are. They are objects that let you intercept and customize operations on other objects. E.g., getting and setting value, checking the inclusion of a property by an object. #ES2015 #ExploringES6

Among these types of reflective metaprogramming, ES5 doesn't support intercession. Proxies exist to fill this gap. #ES2015 #JavaScript #ExploringES6

Besides having the pitfall described in Exploring ES6 JavaScript Set might be used to find out a number of unique characters in the string. #JavaScript #JS #ExploringES6 #JavaScriptTip

Generator not only generates in #JavaScript but also consumes data. Please notice that passing data appears on the second and third calls of next() method. #ExploringES6 #JavaScript #ES6 #ES2015

You can redefine default then() behavior if you resolve Promise with thenable object, the one with then interface. #JavaScript #ES2015 #ExploringES6

Always thought what race() method of a Promise in #JavaScript might be used for. It appears to be quite useful when implementing request timeout. #ES2015 #ExploringES6

You can block browsers reaction to any action by running this simple function. But somehow browser remembers your actions and applies them after synchronous part of the code is finished. Do you know how? #ES2015 #ExploringES6

Proxies can be used as prototypes in #JavaScript. You can redefine default behavior for getting non-existent values. Do not know if this is a good practice🤔 #ES2015 #ExploringES6

There is an interesting case for using #WeakMap in JavaScript. It is suitable for flexible and reliable encapsulation in classes. I've also read the description of this nice method in Mastering JavaScript Object-Oriented Programming book by @andychiare. #JavaScript #ExploringES6

Iteration and generation are close in #JavaScript. To find out more have a look at the inheritance diagram and read the following part of the chapter: exploringjs.com/es6/ch_generat…. #ExploringES6 #ES6 #ES2015

This scheme describing promises in #JavaScript might not be evident at first, but when the understanding is settled it is useful to overview. Here is the chapter containing it: exploringjs.com/es6/ch_promise…. #ES2015 #ExploringES6
