Using useSelector and useDispatch allows for an alternative to the connect() higher-order component. useSelector can replace map state to props by taking in a function argument that specifies the desired part of the state. On the other hand, useDispatch can replace map dispatch to props. To utilize useDispatch, it can be invoked and stored to a variable such as dispatch. This dispatch variable can then work with allActions imported from the actions folder.

React Native New Architecture
React Native new architecture for managing the visual interface, which makes for better performance, easier to develop and maintain applications and an overall better user experience.
How React Native's new architecture improves performance.
React Native has long been praised for its performance, but with the release of React Native 0.57, the performance has gotten even better. The new architecture is based on the principle of 'write once, run anywhere,' which means that code can be written once and then run on any platform. This is a huge advantage for developers, because it means that they don't have to worry about platform-specific code.
The react native new architecture also includes a number of other improvements, such as a new way to manage memory and a new way to handle animations. These improvements make React Native even more efficient and responsive, which is great news for developers and users alike.
New Architecture.

Node Js Coding Questions and Answers
This article provides Node js coding questions and answers to help you better understand the basics of Node.js development. Get the answers you need to master Node.js coding and take your development skills to the next level.
Reverse a string:
Write a function to reverse a given string in Node.js.
function reverseString(str) {
return str.split('').reverse().join('');
}
Explanation: The reverseString function takes a string as input. It uses split('') to convert the string into an array of characters, then uses reverse() to reverse the order of the array, and finally uses join('') to convert the array back to a string with reversed characters.
Find the first non-repeated character:
Write a function to find the first non-repeated character in a given string in Node.js.
function findFirstNonRepeatedChar(str) {
let charCount = {};
for (let char of str) {
charCount[char] = (charCount[char] || 0) + 1;
}
for (let char of str) {
if (charCount[char] === 1) {
return char;
}
}
return null;
}
Explanation:
The findFirstNonRepeatedChar function uses an object charCount to keep track of the count of each character in the input string. It then iterates through the string twice. First, it counts the occurrences of each character and stores them in charCount. Second, it finds the first character with a count of 1 in charCount and returns it as the first non-repeated character.
