Hoisting in TypeScript Hoisting ek concept hai jo JavaScript aur TypeScript mein hota hai. Is concept mein variable aur function declarations ko unke containing scope ke top par move kiya jata hai compilation phase mein. Yani aap variables aur functions ko unke declaration se pehle bhi use kar sakte hain. Chaliye ek example se samjhein kaise hoisting TypeScript mein kaam karta hai: Variable Hoisting: Variable declaration hoisting ke andar aata hai, lekin assignment nahi. Matlab aap variable ko declare karke usme value assign kar sakte hain, lekin usse pehle uska value undefined hoga. Function Hoisting: Function declarations bhi hoisting ke andar aate hain. Matlab aap function ko declare karke usse pehle bhi call kar sakte hain. Function Expressions: Function expressions hoisting mein nahi aate. Matlab aap unhe declare karne se pehle use nahi kar sakte. Hoisting TypeScript mein clean aur bug-free code likhne ke liye important hai. Variable aur function declarations hoisting ke andar aate hain, lekin function expressions nahi. Is baat ka dhyan rakhe aur organized aur readable TypeScript code likhein! #ArtificialIntelligence #GIAIC #ChatGPT #Typescript #Year2024 #Pakistan #Karachi #MachineLearning #BlockChain #Web3 #Metaverse #Hoisting

React 19 Release and Key Enhancements : The upcoming React 19 brings several anticipated enhancements, particularly around React Server Components and Server Actions. Server Components enable rendering on the server side, improving performance by minimizing JavaScript sent to the client. The new Server Actions feature allows client components to execute server-side functions asynchronously, streamlining data handling and reducing client-server communication overhead. React 19 also introduces simplified handling of ref in function components, removing the need for forwardRef in some cases. These updates aim to make React applications faster, especially for large-scale, interactive apps.

Day - 12 of GFG160 problem of the day Problem name : Smallest Positive Missing Number Code:  public int missingNumber(int[] arr) {     // Your code here     int i = 0;     while(i < arr.length){       if(arr[i] > 0 && arr[i] <= arr.length && arr[i] != arr[arr[i] - 1]){         swap(arr,i,arr[i] - 1);       }       else{         i++;       }     }     for(i = 0; i < arr.length; i++){       if(arr[i] != i + 1){         return i + 1;       }     }     return arr.length + 1;         }   static void swap(int[] arr, int i, int j){     int tmp = arr[i];     arr[i] = arr[j];     arr[j] = tmp;   } Intuition : The code places each number in its correct index (arr[i] == i +1) using swaps, ignoring invalid numbers(negative,zero, or out of range). Once reordered, the first index where arr[i] != i + 1 gives the smallest missing postive number.

✅️ Do Not Use In React 🔥🔥 #followformore Amit Jain ❤️✅️ In React, the `<div>` element is not used directly because React emphasizes a component-based architecture. Instead of directly manipulating the DOM with HTML elements like `<div>`, React components are used to encapsulate and manage both the UI and its behavior. Components are reusable, modular building blocks that can contain HTML, CSS, and JavaScript logic. This approach promotes better code organization, maintainability, and scalability. When working in React, you'll create custom components for different parts of your application, such as headers, footers, buttons, and forms. These components can be composed together to form complex UIs. While you can still use `<div>` elements within your components, the focus is on creating meaningful, purpose-built components that represent specific parts of your UI. 1. #ReactJS 2. #ReactDeveloper 3. #FrontendDevelopment 4. #JavaScript 5. #WebDevelopment 6. #UIUX 7. #CodeNewbies 8. #SoftwareEngineering 9. #TechCommunity 10. #LinkedInNetworking 11. #ReactFramework 12. #ReactComponents 13. #ReactNative 14. #ReactRouter 15. #ReactHooks #Linkdin #hiring
