JavaScript, was a simple scripting language for browsers, and had its share of quirks: lack of block scoping, clunky object-oriented patterns, awkward module systems, and verbose string manipulation. In 2015, JavaScript introduced a host of improvements to solve these problems evolving into a robust programming language used on both client and server sides, making JavaScript cleaner, more powerful, and easier to manage.
A custom event is a user-defined DOM event you create and dispatch in your application. Once you dispatch a custom event, you can listen for it just like any other DOM event using addEventListener. This makes it easy for any part of your app to react—regardless of who fired it or where. Use them when built-in events (like click, submit, etc.) are too limiting or when you want to broadcast state changes across components or even separate apps loaded onto the same website.
You can debug JavaScript unit tests running in Node.js (like Jest or Mocha) by launching the test runner with inspection enabled. Use the following command to start tests and pause on the first line:
node --inspect-brk ./node_modules/.bin/jest --runInBand
The --inspect-brk flag starts the V8 inspector and stops at the first line. Adding --runInBand ensures tests run in a single process, which is essential for reliable debugging.
JSONPlaceholder is a free, open-source mock REST API service offering realistic example data (including users, posts, comments, todos, and more) for prototyping and testing front-end applications—no sign-up or backend needed. It supports standard HTTP methods, though only GET requests return persistent data.
Semantic Versioning uses the format major.minor.patch:
In package.json, dependency ranges control allowed updates:
"~1.2.3" or "1.2.x" → versions ≥1.2.3 <1.3.0"^1.2.3" or "1.x" → versions <2.0.0"*" or "x" → any version
export and import keywords to share and reuse code across different files.
There are two main ways to export code from a module: named exports and default exports.
JavaScript has evolved over the years to support asynchronous programming, allowing us to handle tasks like API calls, file reading, and timers without blocking the main thread. One of the most important tools for handling asynchronous operations in JavaScript is the Promise. In this post, we'll break down what a JavaScript Promise is, how to use it, and some common patterns that make asynchronous programming more manageable.
I have always used this blog sparsely to highlight really big events, but i think it is time for me to put some more effort into keeping this more updated. I want to really dive into my knowledge about web development and just share my thoughts more often.
I built a website for my Mother-in-law who owns a small uniform shop in Tyler, Tx. I am proud of her accomplishment, it isn't easy being a small business owner. There are lot of taxes and unforeseen costs, but small businesses in the private sector are the back bone of America!! She has a few contracts with schools in the Tyler TX area. Used "Wix" for the first time to see how easy it is. It isn't as flexible as i would like, but it did make a month long project only take 2-3 days! You should visit Lollipop's Uniform Shop and order some school uniforms for your kids, she has good prices and is a very friendly person to do business with!!
