#XState

JavaScript and TypeScript finite state machines and statecharts for the modern web.

Statecharts are a formalism for modeling stateful, reactive systems. ⚡️

This is useful for declaratively describing the behavior of your application, from the individual components to the overall application logic. 🗣

#NGXS ✨

NGXS is a state management pattern + library for Angular. 🅰️

It acts as a single source of truth for your application's state, providing simple rules for predictable state mutations. ⚡️

NGXS is modeled after the CQRS pattern popularly implemented in libraries like Redux and NgRx but reduces boilerplate by using modern TypeScript features such as classes and decorators. 🔥

NGXS tries to make things as simple and accessible as possible. 🧩

There can be a lot of boilerplate code in state management, thus a main goal of NGXS is to reduce boilerplate allowing you to do more things with less. 💎

#Objects Should Be #Immutable 🤫

In object-oriented programming, an object is immutable if its state can’t be modified after it is created. 🤞🏻

In Java/C#, a good example of an immutable object is String.✅
Once created, we can’t modify its state. We can request that it creates new strings, but its own state will never change. ❌

However, there are not so many immutable classes in JDK. Take, for example, class Date. It is possible to modify its state using setTime(). 🕒

This is an incomplete list of arguments in favor of immutability ⚡️:

• Immutable objects are simpler to construct, test, and use
• Truly immutable objects are always thread-safe
• They help to avoid temporal coupling
• Their usage is side-effect free (no defensive copies)
• Identity mutability problem is avoided
• They always have failure atomicity
• They are much easier to cache
• They prevent NULL references, which are bad

Let’s discuss the most important arguments one by one.

Google celebrated its 21st birthday with an adorable and special doodle today. The search engine was founded by two Stanford Ph.D. students, Sergey Brin and Lawrence (Larry) Page, 21 years ago in September 1998.

Larry and Sergey invented Google in their dormitories at Stanford in California. The two had published a paper about launching a prototype of a large-scale search engine.

Before discovering Google, the two had also developed a search algorithm known as Backrub’. However, the two zeroed in on the name Google for their project because it resembled with the name googol which is a mathematical term meaning 10 raised to the power of 100.

In fact they wrote about this in their paper too, "We chose our systems name, Google, because it is a common spelling of googol, or 10100 and fits well with our goal of building very large-scale search engines."

C# Interfaces: Dangerous Assumptions in Default Implementation ⚠️

One of the features that is being promoted about C# 8 interfaces is that we can add members to an interface without breaking existing implementers. ✅

But we can cause a lot of pain if we aren't careful. 🤷🏻‍♂️

Let's look at some code that makes bad assumptions so that we can understand the importance of avoiding these problems. ⛔️
