About Memoized

Memoized is an interview preparation platform built specifically for JavaScript and TypeScript engineers. Instead of generic algorithm courses with pseudocode, it teaches data structures and algorithms through modern ES6+ JavaScript, using structures such as Map, Set and WeakMap.

The curriculum has two tracks: data structures and algorithms, and advanced JavaScript concepts such as closures, prototypes, event loops, this binding and hoisting. It lists more than 15 core topics, curated interview questions, worked explanations and patterns such as async and await, with code examples like a debounce function.

The site offers free theory and coding practice and links to a pricing page for the fuller curriculum. It also runs a blog and suits web developers preparing for front-end or full-stack technical interviews.
