freeCodeCamp·4yHow to Prepare for React Interviews – Front-End Technical Interview Guide
A polyfill is a custom implementation of native JavaScript functions. The.map() polyfill method takes in a callback that gets executed inside the myMap body. This is nothing but the length of the array through which theMyMap function is called. Since map() returns a new array, we create an empty array and push the results into it. In order to implement debouncing, let's take an example.
Community Picks·4yPlease Stop Using Local Storage
Local storage is just one big old JavaScript object that you can attach data to (or remove data from) Local storage provides at least 5MB of data storage across all major web browsers. This is a fairly low limit for people building apps that are data intensive or need to function offline. If the app you're using doesn't fit the above description: don't use local storage.

DEV·4yReactjs Protected Route
React Router provides a convenient way to define protected routes that require authentication. By default, these routes are treated as public routes and anyone can access them. To create a protected route, you need to use the React Router Route component and specify the path that you want to protect.

asayer·3yBuilding Chrome Extensions for Beginners -- Part 1: Theory
The primary goal of this series is to introduce the basic concepts of Chrome Extensions. At the end of the series, you will have a Pomodoro timer extension built with Javascript. To build any Chrome extension, we must rely on the Chrome developers’ documentation. This is the single source of truth for anything extension related.
freeCodeCamp·3yThe Best Backend as a Service for your React App
Firebase has dominated the backend-as-a-service space for many years, but Supabase has emerged as a great alternative. Supabase allows you to take your code and deploy it wherever you like. You can build your app, deploy it to Supabase's servers, or you can Deploy it to your own hosting service.

Quastor Daily·4yThe Architecture of Databases
Quastor is a free Software Engineering newsletter that sends out summaries of technical blog posts, deep dives on interesting tech and FAANG interview questions and solutions. Today we’ll be talking about the Architecture of Databases. The various components: Transport System, Query Processor, Execution Engine, and the Storage Engine. How these components interact with each other.
Hashnode·4yLocal Storage and Session Storage (JavaScript)
Local storage and session storage store key-value pairs. Local storage stores an array as a string, while session storage stores a pair. To get an array from local storage, we use JSON.parse. In order to remove a particular key- value pair, we can use localStorage.remove.

This reference will outline the most popular layers and development environments for Web3 development. It includes tools to help you deploy to those layers. How to build around wallet identities and use crypto sign-in. Storage. Creating permanent data storage using P2P tech. API. Accessing main networks directly to pull information.
Robin Wieruch·4yReact Hook: useLocalStorage
A neat custom React Hook that shows how to use local storage in React to store state. You can just use it in any React component and it allows you to write and read state. The hook is only there as a learning experience though. If you rely on the local storage for your React application in production, you should check out more widely used hooks.
Community Picks·4yImplementing clean architecture in Go
Go It has been written a lot about the clean architecture in Go It. Its main value is the ability to maintain free from side effects domain layer. This is accomplished by writing dependency-free core domain logic and external adapters. In this article, we'll have a look at how clean architecture is implemented with a sample Go project. In order to signal in case we're unable to proceed we take advantage of Go multiple return value feature.
