JavaScript Async/Await Tutorial for Beginners

·2 views

Async/await is a cleaner way to work with promises in JavaScript. Mark a function with async, then put await in front of a promise to pause that function until the promise settles, and use try/catch to handle errors. Your asynchronous code ends up reading top to bottom like normal code. In this async/await tutorial I start from the basics and work up to running tasks in parallel, using fetch safely, retrying and the mistakes I made along the way. All examples are ES modules (.mjs files) that I ran with Node.js 20, and the comments at the end of each block show the real output.

Cutting Beacon State Storage by ~97%: Validator Sectors with Structural Sharing

A design prototype. I’d like your feedback before I build the reconstruction measurements. Storing full beacon states at regular intervals costs roughly 3 TB. Diffing against a base reference (eth-state-diff) brings that down to about 400 GB. But ~85% of a beacon state is the validators list, which barely changes.

Building TimeZoneCal: An Ultra-Fast, Zero-Dependency Timezone and Meeting Suite with Astro, Tailwind CSS v4, and Native JavaScript

Managing international timezones, coordinating distributed engineering teams, and debugging epoch timestamps remain persistent challenges in modern software development. While many timezone calculators exist, most are cluttered with heavy third-party bundle sizes, dated user interfaces, and inaccurate Daylight Saving Time (DST) calculations. In this article, we examine the architecture, engineering decisions, and implementation details behind TimeZoneCal (timezonecal.com)—a high-performance, zero-dependency web application built with Astro 6, Tailwind CSS v4, and native browser JavaScript.

Python List Comprehension Examples Explained

A Python list comprehension builds a new list in one line by writing [expression for item in iterable], with an optional if at the end to filter items. It replaces the "make an empty list, loop, append" pattern. Below are the list comprehension examples I actually use, from the basic form to filtering, if/else, nested loops and the mistakes that tripped me up. When I started learning Python, comprehensions looked like a puzzle. Once I learned to read them out loud, they became one of my favourite parts of the language.
