Algorithms
Algorithms are the repeatable problem‑solving patterns we use when brute force is no longer good enough. In web development they show up far beyond interview prep: searching, sorting, caching, scheduling, parsing, and state‑heavy UI logic all rely on algorithmic judgement. A lot of the articles here overlap with LeetCode, but the category is broader than that; it is about learning the techniques that make difficult problems easier to reason about in JavaScript and TypeScript.
Below you will find a subset of articles from my blog specifically about Algorithms. This is an area that I have worked with for many years, and have managed to write about quite a few times. There are thirty‑seven collected together for you below.
