Description: Function memoization is an optimization technique that aims to improve application performance by caching the results of previously computed functions. This technique is particularly useful in situations where functions are costly in terms of execution time and are repeatedly invoked with the same arguments. By storing the results of these functions, the need to recalculate the result is avoided, which can lead to a significant reduction in processing time. In many programming languages, memoization can be easily implemented using objects or maps to store results. This technique not only improves application efficiency but can also contribute to a better user experience by reducing wait times. Memoization is particularly effective in recursive algorithms, such as calculating Fibonacci numbers, where multiple redundant calculations can occur. In summary, function memoization is a powerful strategy that allows for optimizing application performance by avoiding unnecessary calculations, resulting in more efficient and faster code.
