To clarify this mumbo jumbo, we'll use the classic example of the Fibonacci sequence. Higher Order Functions: Functions that operate on other functions, either by taking them as arguments or by returning them.You can read more about them here and here. Closures: The combination of a function and the lexical environment within which that function was declared.The concept of memoization in JavaScript relies on two concepts: ![]() Memoization is a simple but powerful trick that can help speed up our code, especially when dealing with repetitive and heavy computing functions. In simpler words, it consists of storing in cache the output of a function, and making the function check if each required computation is in the cache before computing it.Ī cache is simply a temporary data store that holds data so that future requests for that data can be served faster. It does this by storing computation results in cache, and retrieving that same information from the cache the next time it's needed instead of computing it again. In programming, memoization is an optimization technique that makes applications more efficient and hence faster. ![]() Later on we will give practical examples for JavaScript and React. We will start by talking about what memoization is and when it's best to implement it. Hi everyone! In this article we will talk about memoization, an optimization technique that can help make heavy computation processes more efficient.
