In this article series, we embark on a journey through the realm of custom React hooks, discovering their immense potential for elevating your development projects. Our focus today is on the "useStateWithHistory" hook, one of the many carefully crafted hooks available in the collection of React custom hooks.
useScript can be used in various scenarios. For instance, you can load external libraries like jQuery, enabling you to harness its powerful functionalities without adding bulk to your bundle. Additionally, you can load analytics scripts, social media widgets, or any other script necessary for your application's dynamic behavior.
One of the major advantages of using useRenderCount is its simplicity. By abstracting the logic into a reusable hook, you can easily integrate it into any component without cluttering your codebase. Additionally, it provides a clear and concise way to monitor render behavior, which can be crucial for performance optimization and debugging.
This custom hook can be a game-changer in various scenarios. For instance, you can utilize usePrevious to compare and visualize changes in data, track state transitions, or implement undo/redo functionality. Additionally, it can be valuable in form handling, animations, and any situation where having access to the previous value is crucial for your application's logic.
The intuition is to employ a depth-first search (DFS) approach through the tree.
During each step in the traversal, we perform the following key calculations:
1. Determine the path that ends at the current node.
2. Compute two different subtree paths that traverse the current node.
3. Maintain an array that keeps track of the cases where paths contain either 0 or 1 prime number.
This method allows us to efficiently count the valid paths in the tree while considering the presence of prime numbers.
One of the key advantages of useOnScreen is its simplicity. With just a few lines of code, you can detect if an element is visible and respond accordingly. This can be immensely useful in scenarios where you want to trigger animations, lazy load images, or load additional content as the user scrolls.
One of the main advantages of "useOnlineStatus" is its simplicity. By importing and using this hook in your component, you can effortlessly access the online status of the user. The hook internally uses the "navigator.onLine" property to determine the initial online status and dynamically updates it whenever the user's connectivity changes.
One of the key advantages of this custom hook is its simplicity and reusability. With just a few lines of code, you can effortlessly implement responsive behavior throughout your application. Whether you need to conditionally render components, apply specific styles, or trigger different functionality based on screen size, useMediaQuery has got you covered.
One of the key advantages of useLongPress is its simplicity. By utilizing this hook, developers can easily define a long-press action on any element in their React application. With just a few lines of code, the hook takes care of handling the intricacies of tracking the long-press duration and triggering the associated callback function.
One of the key advantages of useGeolocation is its simplicity. By encapsulating the complex logic required for geolocation access and handling, this hook provides a clean and reusable solution. The hook automatically handles the loading state, updating it when geolocation data is being fetched, and sets the error state if any issues arise during the process.
One of the key advantages of useFetch is its simplicity. By abstracting away the fetch logic into a reusable hook, developers can quickly and effortlessly make HTTP requests and handle responses without repetitive boilerplate code. With just a few lines, useFetch handles the network request, parses the JSON response, and provides the resulting data.
The useEventListener hook is a versatile tool that can be used in a wide range of scenarios. Whether you need to capture keyboard events, listen for scroll events, or interact with user input, this hook has got you covered. Its simplicity and elegance make it an ideal choice for any React project, from small-scale applications to large-scale enterprise solutions.
One of the key advantages of useDeepCompareEffect is its ability to prevent unnecessary re-renders. By performing a deep comparison between the current and previous dependencies, the hook intelligently determines if the effect should be triggered, leading to optimized performance in scenarios where shallow comparisons fall short.
The useDebugInformation hook can be applied in various scenarios. For instance, imagine you're working on a complex form component where certain props trigger updates or affect rendering. By utilizing useDebugInformation, you can easily monitor how these props impact your component's performance and whether unnecessary re-renders are occurring. Additionally, the hook can be invaluable when investigating why a specific component is not updating as expected or when fine-tuning optimizations in a performance-critical application.
O(max(nums) * log(max(nums)) + n * log(n)). Accounting for computing prime scores, using the stack to compute next greater elements, and sorting the tuples.
O(max(nums) + n). Considering the space required for arrays and the stack used for computation.
This custom hook is particularly beneficial in scenarios where you need to handle user input, such as search bars or form fields, where you want to delay the execution of an action until the user has finished typing or interacting. It's also useful for optimizing network requests, ensuring that requests are sent only after the user has stopped typing or selecting options.
LeetCode, Hard, last two problems: 2809. Min Time to Make Array Sum At Most x & 2813. Max Elegance of a K-Length Subseq
2809. Min Time to Make Array Sum: Efficient Swift solution, using dynamic programming, for minimizing time to reach a sum in arrays A and B. Time: O(n²), Space: O(n).
2813. Max Elegance of K-Length Subseq: Swift code for elegantly selecting unique k-length subsequences with profit and categories. Solution uses sorting and iteration. Time: O(nlogn), Space: O(n).
One of the main advantages of "useDarkMode" is its simplicity. With just a few lines of code, you can enable dark mode in your React application. By invoking this hook, you'll receive the current dark mode state and a function to toggle it.
The "useDarkMode" hook dynamically updates the HTML body class to apply the "dark-mode" styling whenever dark mode is enabled. This approach ensures consistency across all components without the need for manual class manipulation.
Copying text to the clipboard in a React application can be a tedious task. To simplify this process, I've created a powerful custom hook called useCopyToClipboard. With just a few lines of code, this hook streamlines the copy-to-clipboard functionality, providing developers with a hassle-free solution.
One of the key advantages of this custom hook is the ability to update the cookie value. The updateCookie function, returned by useCookie, enables you to modify the value of the cookie. By invoking this function with a new value and optional options, such as expiration or path, you can instantly update the cookie.
