海外TECH	DEV Community	Using Namespace std;" in C++: Why It's Considered Bad Practice	https://dev.to/iamcymentho/using-namespace-std-in-c-why-its-considered-bad-practice-2adf	Using Namespace std quot in C Why It x s Considered Bad PracticeIn C you might often come across the line using namespace std It seems convenient but it s often discouraged in professional coding practices In this guide we ll explore why this seemingly innocent line can lead to issues and what better alternatives exist Understanding using namespace std The std namespace in C contains many standard library components including data types functions and objects When you write using namespace std you re essentially telling the compiler to consider all the names in the std namespace as if they re in the global namespace This means you can use names like cin cout and vector without specifying std before them The Problem with using namespace std Namespace Pollution When you bring all of std into the global namespace you risk naming conflicts If your code or any library you re using defines a name that clashes with something in std you ll have a problem Readability In larger projects it can become unclear where a particular name is coming from This can make code harder to understand and maintain Maintenance Challenges If you later need to add a new name to your code that happens to exist in std you ll have to refactor your entire codebase to resolve naming conflicts A Better Practice Explicit Namespace UsageInstead of bringing the entire std namespace into your code consider using specific names from std explicitly Benefits of Explicit Namespace Usage Clarity It s clear where each name is coming from making your code more readable Avoiding Conflicts You won t run into conflicts with names defined elsewhere in your code or in libraries Maintainability It s easier to maintain your code in the long term especially in larger projects Conclusion While using namespace std might seem convenient it s generally considered bad practice due to the potential for naming conflicts and reduced code readability Embracing explicit namespace usage is a better approach ensuring your code remains clean maintainable and free of unexpected issues LinkedIn Account LinkedInTwitter Account TwitterCredit Graphics sourced from Youtube	2023-09-02 07:17:40
海外TECH	DEV Community	Deep dive into understanding Props in React	https://dev.to/hassanshahzadaheer/deep-dive-into-understanding-props-in-react-38g9	Deep dive into understanding Props in React What are Props Props short for properties are a fundamental concept in React Think of them as attributes you pass to a component similar to HTML attributes in tags Props allow you to send data from a parent component to a child component They are read only and help make your components dynamic and reusable Creating Props To create props you include attributes in your component like this lt Contact name Ali gt Accessing Props In your child component you access props using the props object export default function Contact props return lt h gt props name lt h gt Destructuring Props Destructuring allows you to extract props more concisely Example export default function Contact name return lt h gt name lt h gt This is especially useful when you have multiple props Why Use Destructuring Destructuring props makes your code cleaner and more readable It reduces repetition by directly extracting the properties you need It also simplifies access to nested props Example Let s create a simple component that receives and displays user information using props and destructuring ParentComponent js import React from react import UserProfile from UserProfile export default function ParentComponent const user name Ali age city New York return lt UserProfile user user gt UserProfile js import React from react export default function UserProfile user return lt div gt lt h gt user name lt h gt lt p gt Age user age lt p gt lt p gt City user city lt p gt lt div gt Conclusion In React props are like attributes you pass from parent to child components Destructuring props simplifies access and enhances code readability Understanding props is essential for building dynamic and reusable React applications	2023-09-02 07:09:07
