In our previous post on the generator function, Understanding Generator Functions in JavaScript let me break down this code step by step, so you can better understand what’s happening when we combine generator functions with Promises. Here’s the code again:…
Let’s look at a real-life example where two-way communication with generators makes sense. One practical use case is simulating a state machine, where the state of the system can change based on inputs. Example: Vending Machine Simulation In this example,…
In the ever-evolving world of JavaScript, the introduction of ES6 brought several powerful features that improved how we write code. Among these, generator functions stand out for their ability to handle multiple values and asynchronous programming elegantly. In this blog…
You have a simple React component that displays a list of numbers, along with a button that allows you to increase a counter. The list of numbers is filtered based on whether they are even or odd. The problem is…
React useMemo vs useCallback Quiz 1. What does useMemo memorize in React? 2. What is the primary use case for useCallback? 3. In which scenario would you use useMemo? 4. What does useCallback return? 5. True or False: useMemo prevents…
In the world of React, optimizing performance is a common challenge, especially when dealing with complex applications. React provides two powerful hooks — useMemo and useCallback — to help manage this by avoiding unnecessary re-renders and computations. While both serve…
When developing web applications, efficiently storing data in a user’s browser is crucial for a smooth user experience. Two popular storage solutions provided by the Web Storage API are Session Storage and Local Storage. Though they seem similar on the…
