This is a very broad category within my articles which encompasses any aspect of web development, from initial design and architecture to coding, testing, and deployment.
Below you will find a subset of articles from my blog specifically about Development. This is an area that I have worked with for many years, and have managed to write about quite a few times. There are three hundred thirty‑one collected together for you below.

Solve Subarray Sum Equals K with prefix sums and a hash map in TypeScript, including negative numbers, count storage, and why sliding window fails.
Container Queries in CSS. Container Queries in CSS
CSS container queries allow elements to respond to their parent's size rather than the viewport. I explain how they work and how they improve responsive design.
