海外TECH	DEV Community	Introduction to C++	https://dev.to/jagroop2000/introduction-to-c-5385	Introduction to C C is a high performance programming language that is widely used in the development of applications operating systems and other systems software It was developed by Bjarne Stroustrup in as an extension of the C programming language One of the main features of C is its support for object oriented programming OOP In OOP a program is organized around objects which represent real world entities or concepts Each object has its own set of data called member variables or attributes and functions called methods or member functions that operate on that data C also supports other programming paradigms such as procedural programming and generic programming In addition to OOP C has a number of other features that make it a powerful language Low level control C allows you to directly manipulate memory giving you fine grained control over the behavior of your program Performance C is a compiled language which means that it is translated into machine code that can be directly executed by the computer This makes C programs fast and efficient Portability C programs can be compiled for a wide range of platforms including Windows Mac Linux and many others Standardization C is standardized by the International Organization for Standardization ISO which ensures that C programs are portable across different compilers and systems If you re new to programming C might not be the best language to start with as it can be more challenging to learn than some other languages However if you re interested in learning C there are many resources available to help you get started including online tutorials books and courses Why C is prefered for Competitive programming and DSA C is often preferred for competitive programming and data structure and algorithms DSA for several reasons Performance C is a compiled language which means that it is translated into machine code that can be directly executed by the computer This makes C programs fast and efficient which is important for solving problems within tight time constraints Low level control C allows you to directly manipulate memory giving you fine grained control over the behavior of your program This can be useful for optimizing the performance of your code particularly when working with large datasets or complex algorithms Standard library C comes with a standard library that includes a wide range of useful data structures and algorithms such as vectors lists and sets These can be used to implement common DSA problems more efficiently Compatibility Many popular programming contests and judges such as those on platforms like Codechef and LeetCode support C as a submission language This makes it easier to participate in these contests and practice your skills Community C has a large and active community of programmers with many online resources and communities dedicated to competitive programming and DSA in C This can make it easier to find help and resources when learning or practicing these skills It s worth noting that C is just one of many languages that can be used for competitive programming and DSA Other languages such as Python and Java may also be suitable depending on your goals and preferences	2022-12-31 13:27:31
海外TECH	DEV Community	React Cheatsheet for 2023 ✍️	https://dev.to/majdsufian/react-cheatsheet-for-2023-14bd	React Cheatsheet for ️Welcome to my React cheat sheet In this article I ll cover all the common concepts and techniques we use every day when developing in React I ll be covering topics such as React elements element attributes element styles fragments components props children props conditionals lists context and hooks Whether you re an experienced developer or new to React this cheat sheet aims to provide you with a quick reference for all the key concepts and techniques you need to know to build powerful and scalable applications with React So let s get started and dive into my React cheatsheet React Element AttributesJSX requires a different syntax for its attributes Since JSX is really JavaScript and JavaScript uses a camelcase naming convention that is “camelCase attributes are written differently than HTML The most common example is the class attribute which we write as className lt div className App gt lt div gt React Element StylesIn addition to attributes elements can also have inline styles applied to them To set inline styles in React you ll need to use the style attribute and pass in an object containing the desired styles For example lt div style color red fontSize px gt Hello World lt div gt React FragmentsSometimes you may want to render a group of elements without adding an extra DOM node around them In these cases you can use React fragments which allow you to wrap multiple elements in a single container without adding any extra markup To use a fragment you can use the lt gt syntax lt gt lt div gt First element lt div gt lt div gt Second element lt div gt lt gt React ComponentsComponents are the building blocks of a React application and allow you to split your UI into reusable pieces You can create a component by defining a JavaScript function or class that returns a React element For example function MyButton props return lt button gt props label lt button gt React PropsProps short for properties are a way for components to accept data from their parent components When a parent component renders a child component it can pass data to the child component through props For example lt MyButton label Click me gt React Children PropsSometimes you may want to render a component s children inside the component itself To do this you can use the props children property which represents the content between the opening and closing tags of a component For example function MyContainer props return lt div gt props children lt div gt lt MyContainer gt lt p gt Content goes here lt p gt lt MyContainer gt React ConditionalsReact allows you to use JavaScript expressions to conditionally render elements based on certain conditions For example you can use the amp amp operator to only render an element if a certain condition is true isLoggedIn amp amp lt p gt Welcome back lt p gt React ListsReact provides a map function that allows you to render a list of elements based on an array of data For example const items item item item lt ul gt items map item gt lt li gt item lt li gt lt ul gt React ContextReact Context is a way to pass data through the component tree without having to pass props down manually at every level It is often used for global data that needs to be accessible by multiple components such as a user s theme preference or a language setting To create a context you can use the createContext function and provide a default value for the context Then you can use the Provider component to provide the context value to its children and the useContext hook to consume the context value from a component React HooksReact Hooks are a new addition to React that allow you to use state and other features in functional components rather than just class based components There are several built in hooks that provide common functionality such as managing state or performing side effects I am going to cover the essential hooks you absolutely need to know useStateuseEffectuseRefuseContextuseCallbackuseMemo React useState HookThe useState hook allows you to add state to a functional component It returns an array with two elements the current state value and a function to update it You can use the hook like this import useState from react function MyComponent const count setCount useState return lt div gt lt p gt count lt p gt lt button onClick gt setCount count gt Increment lt button gt lt div gt React useEffect HookThe useEffect hook allows you to perform side effects in a functional component such as making an API call or setting up a subscription It takes a function as an argument that will be called after the component renders You can use the hook like this import useEffect from react function MyComponent useEffect gt Perform side effect here return lt div gt My component lt div gt React useRef HookThe useRef hook allows you to create a mutable reference to a DOM element or value It returns a mutable ref object whose current property is initialized to the provided argument or null if no argument is given You can use the hook like this import useRef from react function MyComponent const inputRef useRef null return lt div gt lt input ref inputRef gt lt div gt React useContext HookThe useContext hook allows you to consume a context value from a functional component It takes the context object as an argument and returns the current context value You can use the hook like this import useContext from react const MyContext createContext defaultValue function MyComponent const value useContext MyContext return lt div gt value lt div gt React useCallback HookThe useCallback hook returns a memoized callback function that only changes if one of the dependencies has changed It can be used to optimize the performance of components that rely on expensive functions or callbacks You can use the hook like this import useCallback from react function MyComponent const callback useCallback gt Expensive function or callback dependency dependency return lt div onClick callback gt Click me lt div gt React useMemo HookThe useMemo hook returns a memoized value that only changes if one of the dependencies has changed It can be used to optimize the performance of expensive calculations by only re computing the value when necessary You can use the hook like this import useMemo from react function MyComponent const value useMemo gt Expensive calculation dependency dependency return lt div gt value lt div gt ConclusionIn this article we provided a cheat sheet for some of the most common techniques and concepts used in React development including element attributes styles fragments components props conditionals lists context and hooks By familiarizing yourself with these concepts you ll be well equipped to build powerful and scalable applications with React	2022-12-31 13:12:27
