Master the art of converting callback-based functions to promises in TypeScript for modern async patterns and cleaner code architecture 🚀 Master the art of converting callback-based functions to promises in TypeScript for modern async patterns and cleaner code architecture 🚀 In TypeScript, callback functions are a powerful and widely used concept. Callback functions are functions passed as arguments to other functions and executed at a later time or after a specific event. You can define multiple return values in the type here itself and return multiple data in completion separating with Callbacks are widely used in scenarios such as handling asynchronous operations like reading files, making API calls, or handling events. useCallback(callback, dependencies) callback: The function that you want to memoize.
