TypeScript definitions for lodash.memoize
@types/lodash.memoize provides TypeScript type definitions for the lodash.memoize function, which is a utility for creating memoized versions of functions. Memoization is a technique used to speed up function execution by caching the results of expensive function calls and returning the cached result when the same inputs occur again.
Basic Memoization
This feature allows you to memoize a simple function. The memoized function will cache the result of the function call and return the cached result when the same inputs are provided again.
const memoize = require('lodash.memoize');
function add(a, b) {
return a + b;
}
const memoizedAdd = memoize(add);
console.log(memoizedAdd(1, 2)); // 3
console.log(memoizedAdd(1, 2)); // 3, retrieved from cache
Custom Resolver
This feature allows you to provide a custom resolver function to determine the cache key for storing the result. This can be useful when the default resolver does not meet your needs.
const memoize = require('lodash.memoize');
function add(a, b) {
return a + b;
}
const customResolver = (a, b) => `${a}-${b}`;
const memoizedAdd = memoize(add, customResolver);
console.log(memoizedAdd(1, 2)); // 3
console.log(memoizedAdd(1, 2)); // 3, retrieved from cache
Clearing Cache
This feature allows you to clear the cache of a memoized function. This can be useful when you need to invalidate the cache and force the function to recompute the result.
const memoize = require('lodash.memoize');
function add(a, b) {
return a + b;
}
const memoizedAdd = memoize(add);
console.log(memoizedAdd(1, 2)); // 3
memoizedAdd.cache.clear();
console.log(memoizedAdd(1, 2)); // 3, recalculated
memoizee is a highly configurable memoization library for JavaScript. It offers more advanced features compared to lodash.memoize, such as support for multiple arguments, time-based cache expiration, and more. It is a good choice if you need more control over the memoization process.
fast-memoize is a fast and efficient memoization library for JavaScript. It focuses on performance and simplicity, making it a good alternative to lodash.memoize if you need a lightweight and high-performance memoization solution.
moize is a memoization library that offers a wide range of features, including support for multiple arguments, cache expiration, and custom cache strategies. It is more feature-rich compared to lodash.memoize and is suitable for more complex use cases.
