Memoization
Understand memoization as an optimization technique in JavaScript ES6 that uses caching to reduce redundant function calls. Learn why functions must be deterministic for memoization and how it improves efficiency, especially demonstrated with the Fibonacci sequence. This lesson provides practical insights for optimizing recursive functions and using memoization as a cache to enhance performance.
We'll cover the following...
Exercise:
What is memoization? What are its benefits? What is the necessary condition for using memoization? Illustrate the benefits of memoization using an example.
Remark:
Expect these types of questions when bridging theory with practice. You need to know what you are doing, and you have to write code that runs properly. The task itself is up to your interpretation, so choose the easiest possible solution.
Solution:
Memoization is an optimization technique often used with recursion. We create a lookup table that contains the mapping between the input and the output of the function. If the input has been calculated before, we find the corresponding output in ...
