how to use the memoize function from the underscore library in javascript

To use the memoize function from the underscore library in JavaScript, first, make sure you have included the library script in your HTML file:

<script src="https://underscorejs.org/underscore-min.js"></script>
67 chars
2 lines

Then, you can use the _.memoize function to create a memoized version of any function that takes arguments and returns a value:

index.tsx
function longComputation(a, b, c) {
  // simulate a long computation with arguments a, b, and c
  console.log(`Computing ${a} + ${b} + ${c}`);
  return a + b + c;
}

const memoizedComputation = _.memoize(longComputation);

memoizedComputation(1, 2, 3); // Output: Computing 1 + 2 + 3
memoizedComputation(1, 2, 3); // Output: (no console log output because result is cached)
374 chars
11 lines

The first time you call memoizedComputation, it will compute the result and log the message "Computing 1 + 2 + 3" to the console. The result is then cached, so the second time you call memoizedComputation with the same arguments, it will return the cached result without recomputing and logging the message again.

Note that the _.memoize function uses JavaScript's default object property to store the cached results. Therefore, it will only work with functions that have serializable argument values, i.e., values that can be converted to a string and used as object keys. If you have non-serializable arguments, you should use a different memoization library or write your own memoization function.
