JavaScript Memoization Explained Simply
Memoization is the programmatic practice of making recursive/iterative functions run faster by caching the values that the function returns after its initial execution.
const cache = new Map();
let calculations = 0;
function square(n) {
if (cache.has(n)) return cache.get(n);
calculations++;
const result = n * n;
cache.set(n, result);
return result;
}
console.log(square(8));
console.log(square(8));
console.log(calculations); AI panel
