海外TECH	DEV Community	useState() 🪝	https://dev.to/mihir_chhatre/usestate-4imn	useState 🪝Let us first understand state in React State can be imagined as the data or property that is used within an application These data property values would likely change over time and the State hook in React helps us track amp manage the changing states To use the State hook we need to import it as shown below import React useState from react We can then invoke useState inside the component function and pass an initial state this value can be any type such as string number or object as an argument const count setCountValue useState The useState hook returns an array where the first element corresponds to the current state and the second element is a function that allows us to update the current state Let s get building ️Consider the code for a simple counter functionality import React useState from react const App gt const count setCountValue useState const decrement gt setCountValue prevState gt prevState const increment gt setCountValue prevState gt prevState return lt div gt lt button onClick decrement gt lt button gt lt span gt count lt span gt lt button onClick increment gt lt button gt lt div gt export default App Simplifying the code above useState is called within the component function and an initial state is passed to it This means that when the component is rendered for the first time when the page is loaded initially the counter is set to As mentioned earlier useState returns an array with two elements Here using array destructing the current state is stored in the count variable and the function to update the current state is setCountValue The button triggers the increment function and triggers the decrement function I am using the setCountValue function to update the current state value Let s have a look at a common mistake developers tend to make when trying to update the state using the previous state const decrement gt setCountValue count Why is the above approach an incorrect one to update the state value When we modify the state using the previous state value in the above code we are using the count variable directly we must use the function version of setting state as shown below const decrement gt setCountValue prevState gt prevState prevState is the previous state snapshot that React provides The reason behind using this approach is that the state updating function in React schedules the state update By using the function version to set the state we can ensure that the previous state is always updated latest Diving deeper into useState Each time the state updating function is called the state is updated and the component function from which the useState is initialized is executed again It is also important to remember that useState registers a different state for each component instance and React manages states independently on a per component basis Here are two frequently frequently asked questions when using useState Why does useState use const since the state value is updated gt The way to think about this question is that each time the component is rendered state update function is called a new variable is created and managed somewhere else internally by React Does the default state not override the current state value each time the state updating function is called and the component is rendered gt React keeps track of the first instance where useState was called and prevents any default state overwrites during subsequent component renders Another important concept to understand is how to work with objects and useState const state setState useState count toggle Yes const count state count const toggle state toggle function decrement setState prevState gt return count prevState count The above code is incorrect since the setState update function overrides the previous state with only the updated count toggle Yes is removed The correct way to use an object is to spread the previous state and then set the new state function decrement setState prevState gt return prevState count prevState count Finally lets talk about an advance concept when using useState Consider setting the initial state as a useState a When using state hook the initial state a is called each time the function is run If a computationally complex argument is defined as the initial state it would run during every subsequent component function render leading to a degradation in performance Therefore there is another way to pass state to useState a function version useState gt return The approach runs the initial state function only during the first component render This approach is preferred when we have a computationally intensive initial state The gamut of information around useState can be overwhelming Remember to go slow and understand the concepts as it would you build a base in React	2023-01-27 04:47:10
海外TECH	DEV Community	Intro to Hooks	https://dev.to/mihir_chhatre/intro-to-hooks-39g7	Intro to HooksUsing hooks in React can be daunting My goal through this series is to simplify the different hooks used in React allowing folks to start implementing these concepts into their builds Since this is Part of the series let s scratch the surface on hooks The React documentation defines hooks as Functions that let you “hook into React state and lifecycle features from function components The above definition will make a lot more sense as we go through this series but it is important to remember a few important points when using any hook in React gt Hooks can only be used inside function components and they cannot be used inside class components Hooks must execute in the same order in each component render This essentially means you cannot use a hook inside a conditional block such as if You can always reference the official React documentation to learn more about hooks but since series is about understanding the different hooks I am jumping right into one of the most widely used hooks the State Hook	2023-01-27 04:46:47
海外TECH	DEV Community	Will ChatGPT replace Developer's Job?	https://dev.to/dhruvjoshi9/will-chatgpt-replace-developers-job-37j2	Will ChatGPT replace Developer x s Job In recent years advancements in natural language processing NLP have led to the development of powerful language models such as GPT which has the ability to generate human like text and answer questions with a high degree of accuracy With such capabilities it s natural to wonder if these models will eventually replace the role of developers in the tech industry First it s important to understand what a developer s job entails Developers are responsible for designing coding testing and maintaining software applications They are responsible for ensuring that the software functions properly and meets the needs of the end user They also need to stay current with new technologies and programming languages which requires continuous learning and adaptability Now let s look at the capabilities of ChatGPT It is a language model that has been trained on a massive amount of text data which enables it to generate text that is similar to human writing It can also answer questions and provide information with a high degree of accuracy However it s important to note that ChatGPT is a tool that can be used to assist developers in their work rather than a replacement for their expertise and problem solving abilities For example ChatGPT can be used to generate code snippets which can save time for developers and make their work more efficient It can also assist in natural language processing tasks such as text summarization and sentiment analysis However it s still the developer s responsibility to ensure that the code is correct and efficient and that it meets the needs of the end user In conclusion while ChatGPT and other language models have the ability to assist developers in their work it is unlikely that they will completely replace the role of developers A developer s job involves a wide range of responsibilities and skills that cannot be fully replaced by a language model ChatGPT is a powerful tool but it still requires the expertise and problem solving abilities of a human developer to ensure that software applications are functioning properly and meeting the needs of the end user So don t worry Your Job is secure If you liked reading it please like share and follow You can reach me if you got a complex app development project that may be I am helpful in	2023-01-27 04:39:36
