MobX is the new upcoming state management solution. This blog is all about how to create a simple React-Native app using MobX.
MobX is fast in speed than Redux, its easier to learn & requires less boilerplate code.
Here are some of its main concepts
Stores:
Stores create data sources. A store is basically an ES6 class. the state is automatically derived from a data source by MobX by using ES6 decorators.
1. The store can expose the observable field(s), to which an observer can react. 2. The store can additionally expose some derived observable fields too. Which are pure functions on observable fields? MobX calls them as computed fields. 3. The store can also change the values of observable fields via actions. Only in this way MobX can allow you to change state.

Redux State Management System A Comprehensive Reviewijtsrd
Reactivity is a common trait of JavaScript applications and comes with efficient state management. Any JavaScript application has multiple ways of managing state for example, in React, we can use useState" and "useReducer Hooks. However, another third party library called Redux has grown in popularity to be an efficient state management tool in JavaScript applications. This paper makes an in depth review of the Redux state management system. It is famously used with React as a state management tool and by other JavaScript frameworks as well. Redux is most suitable for applications with frequent updates to the state since Redux has better efficiency in a flux like setup than Reacts Context API.

How to use geolocation in react native appsInnovationM
Geolocation will find your current location and Geocoding gives your address (like City Name, Street Name, etc) by Coordinates (Latitude and Longitude).
What is Geolocation?
The most famous and familiar location feature — Geolocation is the ability to track a device using GPS, cell phone towers, WiFi access points or a combination of these. Since devices area unit employed by people, geolocation uses positioning systems to trace associate degree individual’s whereabouts right down to latitude and great circle coordinates, or more practically, a physical address. Both mobile and desktop devices can use geolocation.
Geolocation is accustomed to confirm zone and actual positioning coordinates, like for chase life or shipment shipments.
As everyone knows, a lot of changes made after API level 26 for optimizing Android system’s performance, the battery uses and other system-level problems which I am writing below:

Understanding of react fiber architectureInnovationM
React v16.0 was released with an update to react core algorithm. This new core architecture is named “Fiber”. Facebook has completely rewritten the internals of React from the ground-up while keeping the public API essentially unchanged, in simple terms it means only changing the engine of a running car. With this release, some new features are also added like Asynchronous Rendering, Portals, Error Boundaries, Fragments (i.e. return array of elements). Incremental rendering is the headline addition to React which adds the ability to split rendering work into chunks.
Automatic reference counting (arc) and memory management in swiftInnovationM
Memory management is a key factor when we developing apps. If a program is using a lot of memory it can affect badly on your device making apps run slowly or even cause crashes. So for that in swift, you can work with Automatic Reference Counting (ARC) to keep your apps memory usage minimal. This doesn’t mean you can forget about the memory in your app but it does take care of most things for you.

Integration of Highcharts with React ( JavaScript library )InnovationM
Highcharts is a front-end javascript library which is made to design the charts on web pages. ReactJS is also a javascript library for UI design. Now If we need to create a chart in ReactJS, there is a good news that several libraries (like ReCharts, Victory, VX, React-JSX-Highcharts, React-VIS etc.) are available which can be used for this purpose.
Serialization & De-serialization in JavaInnovationM
When you create a class, you may create an object for that particular class and once we execute/terminate the program, the object is destroyed by itself (Garbage Collector thread).
Stream concept is introduced in java 1.8 and present in java.util.stream package.It is used to process the object from collection or any group of objects or data source.
How to Make Each Round of Testing Count?InnovationM
We are doing write thing, as we need to check and test all the buttons, textbox, text values, validations, etc. While doing all this we should not forget our audience. We maybe be thinking stuffs in technical way but other non-tech guy will also use this app or website. We have to make it friendlier for them too.
MVP is a design pattern for developers to write their code in more readable, maintainable and

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Mob x in react
1. MobX in React
MobX is the new upcoming state management solution. This blog is all about how to create a
simple React-Native app using MobX.
MobX is fast in speed than Redux, its easier to learn & requires less boilerplate code.
Here are some of its main concepts
Stores:
Stores create data sources. A store is basically an ES6 class. the state is automatically derived
from a data source by MobX by using ES6 decorators.
1. The store can expose the observable field(s), to which an observer can react.
2. The store can additionally expose some derived observable fields too. Which are pure
functions on observable fields? MobX calls them as computed fields.
3. The store can also change the values of observable fields via actions. Only in this way
MobX can allow you to change state.
MobX has some core concepts:
• Observables
• Computed Values
• Reactions
• Actions
Observables:
Observables extend functionality to subscribe to their changes.
We can list down our class properties with @observable decorator & using observers, check their
values.
These observers will be updated accordingly every time the values will change.
Computed values:
Computed values are derived from observables. These values will be automatically updated
when the observables will change.
It should be kept in mind that, ‘computed’ has to be observed in order to be updated
Reactions:
Reactions are identical to computed values, but they are used to produce side-effects instead of
returning new value (patching DOM, making network requests, etc.).
MobX provides 3 reaction functions when autorun and reaction
• When
2. when it takes two functions: predicate and effect. It executes and checks predicate until it
returns true, and then executes the effect function. After that, it disposes and stops reacting
checked property.
• Autorun
autorun is used in specific cases where you want a reactive function that will get fired every time
the checked value is updated. Unlike computed it doesn’t have to be checked itself.
• Reaction
the reaction is like autorun but gives you more control over what properties to check. It takes two
functions, namely data-function and side-effect-function. data-function is observed and returns
data that is used in side-effect-function.
Fig. 1.1: The MobX lifecycle
Actions:
Actions are responsible for altering the state.we can use them to explicitly mark that function
with @action decorator.
This decorator takes a function and wraps it into a transaction, untracked and allows state
changes.
• Transaction
the transaction is used to batch together updates in the state so until & unless that function is
completed, no observers will be notified. So we can update various properties at once.
• Untracked
With the help of untracked, we can run code without establishing observers (just like reactions, or
unlike computed’s)
3. • Allow State Changes
allow state changes is used to allow or reject state changes for certain functions. By default
allows an action to make changes (and disallows for computed and observer).
Observers:
Honestly, observers aren’t part of MobX core. They are provided by the mobx-react package.
They are used to enable views to “observe” observables and re-render on change.
Let’s explore a simple ValueStore. It provides an observable field named count value and
actions increase_value and decrease_value to change the value.

// @ flow

class ValueStore{
@observable countValue=0;
@action increase_value()={
this.countValue+=1;
}
@action decrease_value()={
4. 16
17
18

this.countValue-=1;
}
}
export default ValueStore;
Here is a look at a component that keeps track of count value and re-renders every time the
count value gets changed.

render() {
5. 13
14
15
16
17
return <Text>Count: {this.props.valueStore.count}</Text>;
}
}
By decorating class with @observer, MobX can infer reactions to the changes in store &
automatically subscribe to them and re-render component on getting changes.
@inject is a MobX decorator that will provide component props with the mentioned store.
MobX provides a React Provider that can be made as a parent component for all the
components of your application. A MobX provider should be initialized with all the stores that you
may want to be injected into your components.
