It’s critical for developers to create apps that function well. A one-second delay in load time can result in a 26% drop in conversion rates, research by Akamai has found. React memoization is the key to a faster client experience—at the slight expense of using more memory.

Memoization is a technique in computer programming in which computational results are cached and associated with their functional input. This enables faster result retrieval when the same function is called again—and it’s a foundational plank in React’s architecture.

React developers can apply three types of memoization hooks to their code, depending on which portions of their applications they wish to optimize. Let’s examine memoization, these types of React hooks, and when to use them.

Memoization in React: A Broader Look

Memoization is an age-old optimization technique, often encountered at the function level in software and the instruction level in hardware. While repetitive function calls
