Debugging Async/Await with Promises in JavaScript

I’ve broken down 3 golden rules to write predictable, bug-free state management in Redux — all in a visual, easy-to-digest format. Whether you’re a React beginner or a frontend pro, these rules will help you: ✅ Write pure reducers ✅ Keep state immutable ✅ Keep reducers synchronous 💡 Carousel slides include short explanations and code examples so you can apply them instantly in your projects. Check it out and let me know: Which rule do you think is most often broken? #Redux #ReactJS #ReduxToolkit #FrontendDevelopment #JavaScript #WebDev #HamzaNazir

3 Things I Stopped Doing as a Developer 1.Overengineering MVPs – shipping fast taught me more than perfecting ideas. 2.Ignoring documentation – now I document as I go. Saves hours later. 3.Chasing new frameworks #LearnTechWithFola #TechWithFola #30DaysChallenge #SoftwareEngineering #EcommerceDev #ReactJS #NextJS #JavaScript #TypeScript #BuildInPublic#Ai #Aibuilder

🚀 Using `test()` Method for Boolean Matching (JavaScript) The `test()` method of a regular expression object returns `true` if the pattern matches the string, and `false` otherwise. It's a simple and efficient way to check if a string conforms to a specific pattern. The `test()` method does not return any information about the matched substring, only whether a match exists. It's ideal for validation scenarios where you only need a boolean result. #JavaScript #WebDev #Frontend #JS #professional #career #development

🚀 Mocking Dependencies in JavaScript Tests Mocking is a technique used in unit testing to isolate the code being tested from its dependencies. When a unit of code relies on external resources or other modules, mocking allows you to replace those dependencies with controlled substitutes. This ensures that the test focuses solely on the behavior of the unit under test, without being affected by the external factors. Frameworks like Jest provide built-in mocking capabilities using functions like `jest.fn()` and `jest.mock()`. Mocking helps to create predictable and reliable tests. #JavaScript #WebDev #Frontend #JS #professional #career #development

🚀 The `setTimeout()` Function (JavaScript) The `setTimeout()` function allows you to execute a function after a specified delay in milliseconds. It is a fundamental tool for creating asynchronous behavior in JavaScript. The function passed to `setTimeout()` is added to the task queue and executed by the event loop when the delay has elapsed and the call stack is empty. `setTimeout` is often used to defer execution or schedule tasks for later. #JavaScript #WebDev #Frontend #JS #professional #career #development

Today, I learned about the setTimeout() function in JavaScript. It allows us to delay the execution of a function for a specified amount of time (in milliseconds). In this example, the message appears after 2 seconds, showing how we can control timing in JavaScript. It’s useful for animations, notifications, and delaying actions in web applications.

🚀 Importing into JavaScript Modules The `import` keyword is used to bring in variables, functions, or classes from other modules. You can import named exports using curly braces `{}` and specifying the names of the exported values. You can import the default export using any name you choose, without curly braces. Modules must be properly linked and configured in your project to ensure that imports resolve correctly. Importing allows you to reuse code and build complex applications from smaller, manageable components. #JavaScript #WebDev #Frontend #JS #professional #career #development
