海外TECH	DEV Community	Packages and Import in Go (Golang)	https://dev.to/diwakarkashyap/packages-and-import-in-go-golang-3adk	Packages and Import in Go Golang Packages and Import in Go Imagine you re cooking and you have different boxes of ingredients Each box has a label and contains specific ingredients for a particular recipe In the Go programming language these boxes are like packages They group together related functions and other pieces of code Explore the Go standard library What it means Go has its collection of ready made boxes or packages that offer many tools It s like a chef s toolkit In simple terms Just like a chef doesn t need to grow their vegetables Go developers don t need to write common functions from scratch They can use the tools Go provides Learn how to import packages What it means Before you can use the tools in a box you have to open it or import it This is like saying I want to use the tools from this box in my recipe In simple terms It s like opening a specific spice box from your kitchen shelf to use the spices in your dish Create your own packages What it means Apart from using the ready made boxes from Go you can also create your boxes with your unique ingredients or tools In simple terms If you don t find the right spice mix in the market you can make your blend and store it in a box Later you can use it in multiple dishes In Conclusion When you re programming in Go packages help you keep things organized You can use ready made packages or you can make your own To use the tools or functions inside a package you need to import it just like opening a box to use the ingredients inside Exploring Go Standard Library Official Documentation The best place to start exploring the Go standard library is the official documentation It offers an organized list of packages with descriptions Some key packages include fmt Formatting and printing net http Handling HTTP requests and building web servers os OS level functionality like file handling strconv Convert strings to basic data types math Basic mathematical operations sort Sorting slices sync Synchronization primitives io and io ioutil Interfaces for I O operations Importing Packages In Go you can use the import keyword to include packages in your source code package mainimport fmt math func main fmt Println Square root of math Sqrt Creating Your Own Packages Structure Organize your code into different directories Each directory would correspond to a single package For instance if you have a project structure like myproject ├ーmain go└ーmypackage └ーmypackage goHere main go can be in the main package and mypackage go would be part of the mypackage Package Declaration At the start of every Go file you declare the package it belongs to mypackage mypackage gopackage mypackagefunc MyFunction string return Hello from mypackage Using Your Package Now in main go you can import your custom package main gopackage mainimport fmt mypackage func main fmt Println mypackage MyFunction When you run main go it will print Hello from mypackage Public vs Private In Go if an identifier like a function variable or type starts with an uppercase letter it s exported public If it starts with a lowercase letter it s unexported private and can t be accessed from outside its package Go Modules As your project grows and you start using external packages or want to make your package usable by others you should learn about Go Modules They are the official dependency management solution for Go Using go mod init you can initialize a new module and with go get you can fetch dependencies Summary Explore the Go standard library using the official documentation Use the import keyword to use packages in your code Structure your codebase into directories to create packages Declare the package at the start of each Go file Use uppercase for exported identifiers and lowercase for unexported Learn about Go Modules for dependency management as your projects grow By mastering packages and imports in Go you can create organized and modular code taking full advantage of the rich standard library and the broader ecosystem Thank you for reading I encourage you to follow me on Twitter where I regularly share content about JavaScript and React as well as contribute to open source projects and learning golang I am currently seeking a remote job or internship Twitter GitHub Portfolio	2023-08-26 12:52:33
海外TECH	DEV Community	React.js Hooks: A Quick Guide	https://dev.to/pulkit30/reactjs-hooks-a-quick-guide-1le2	React js Hooks A Quick GuideAs developers we re constantly looking for ways to build cleaner more efficient and more modular code React a popular JavaScript library for building user interfaces has recently introduced a game changing feature called Hooks In this blog post we ll dive into the world of React Hooks understand their purpose and learn how to use them with real life examples So let s get hooked on Hooks What are React Hooks React Hooks are a set of functions that allow us to hook into React state and lifecycle features from function components They were introduced in React to enable developers to write cleaner and more reusable code by eliminating the need for classes and simplifying complex components Some of the most common Hooks are useState useEffect and useContext useState The useState Hook allows us to add state to our functional components It s a great replacement for the old setState method in class components Example import React useState from react function Counter const count setCount useState return lt div gt lt p gt clicked count times lt p gt lt button onClick gt setCount count gt Click me lt button gt lt div gt export default Counter In this example we create a simple counter component We use the useState Hook to initialize the count state variable to and provide a setCount function to update the state When the button is clicked the setCount function is called to increment the count by useEffectThe useEffect Hook allows us to perform side effects like data fetching or updating the DOM in our functional components It replaces lifecycle methods like componentDidMount componentDidUpdate and componentWillUnmount Example import React useState useEffect from react function User userId const user setUser useState null useEffect gt const fetchUser async gt const response await fetch userId const userData await response json setUser userData fetchUser userId return lt div gt user lt p gt user name lt p gt lt p gt Loading lt p gt lt div gt export default User In this example we create a User component that fetches a user s data based on their userId We use the useEffect Hook to make an API call when the component mounts or when the userId changes The useEffect Hook takes two arguments a function to perform the side effect and an array of dependencies In this case the dependency is the userId useContextThe useContext Hook allows us to access the value of a given context without using the traditional Context Consumer component It simplifies the process of retrieving context values in our components Example import React useContext from react import ThemeContext from ThemeContext function ThemedButton const theme useContext ThemeContext return lt button style background theme background color theme foreground gt I am a themed button lt button gt export default ThemedButton In this example we create a ThemedButton component that uses the useContext Hook to access the theme values from a ThemeContext We then apply the theme s background and foreground colors to the button s style Conclusion React Hooks have truly revolutionized the way we build modern web applications By understanding and implementing Hooks like useState useEffect and useContext we can write cleaner more efficient and more modular code So go ahead give Hooks a try and watch our React development skills soar to new heightsIn Next Blog I ll cover more hooks with proper examples Stay tuned	2023-08-26 12:30:35
