What is memoization and how would you implement it for a pure function in JavaScript?

Key points

  • Memoization optimizes function performance by storing and reusing previous results
  • The cache is typically implemented using a Map or object to store key-value pairs
  • The key for the cache is often generated by serializing the function arguments
  • Memoization is particularly useful for recursive functions or functions with complex calculations
