Exploring JavaScript Symbols
Published: at 02:11 PMDeep dive into JavaScript Symbols - what they are, why they matter, and how to use them effectively
Deep Cloning Objects in JavaScript, the Modern Way
Published: at 01:12 PMThis article explains JavaScript’s Structured Clone algorithm, which enables deep copying of complex objects. It covers use cases, limitations, and how Structured Clone differs from JSON serialization, helping developers safely duplicate data without unexpected behavior
Building a Single-Page App with htmx
Published: at 08:16 AMThe article explores how to use htmx, a modern tool that extends HTML with AJAX-like functionality, to create a single-page application (SPA) without heavy JavaScript frameworks. It demonstrates building an interactive app by sending asynchronous requests and updating page content dynamically, all while maintaining a simple, server-driven approach. This method avoids the complexity of client-side frameworks like React or Vue, making it an appealing choice for lightweight applications.
Unleash JavaScript's Potential with Functional Programming
Published: at 03:13 PMThe article on functional programming with JavaScript discusses how this approach can unlock greater potential in coding. It explains how functions are treated as first-class citizens, enabling cleaner, more modular, and reusable code. Key concepts like higher-order functions, immutability, and pure functions are covered, emphasizing their benefits for writing more predictable and testable code. This approach encourages a shift away from traditional imperative coding towards a declarative style that simplifies complex logic.
The Popover API: Your New Best Friend for Tooltips
Published: at 03:09 PMThe article discusses the Popover API, which simplifies the creation and management of tooltips, popovers, and other overlays. It provides developers with a standardized, accessible way to position popovers with HTML and JavaScript. New CSS features like anchor and @position-try help customize popover placement, making it easier to handle viewport overflow and styling. These improvements reduce reliance on complex JavaScript or third-party libraries, although browser support for some features may still be limited.
jaqt: javascript queries and transformations
Published: at 03:34 PMJAQT is a JavaScript library that provides SQL and GraphQL-inspired functions, Array.select() and Array.where(), for working with arrays and objects. It enhances the native Array.map() and Array.filter() methods by adding syntactic sugar for easier querying, without introducing a custom query language. This allows users to perform complex data transformations using plain JavaScript, making the code both powerful and intuitive. The library is lightweight and flexible, designed for scenarios where ease of use is preferred over performance improvements.
OpenAI is shockingly good at unminifying code
Published: at 01:26 PMThe article explains how OpenAI tools assist in reverse-engineering minified JavaScript. It uses an example of a complex ASCII art generator to show how ChatGPT can interpret the code, making it more readable by converting it to TypeScript. The article highlights the utility of AI in understanding and debugging obfuscated code.
Front End Interview Handbook
Published: at 02:57 PMThe Frontend Interview Handbook is a comprehensive resource designed to help developers prepare for frontend job interviews. It covers essential topics like HTML, CSS, JavaScript, and algorithms, offering practice questions, tips, and detailed explanations. The handbook also provides guidance on how to approach interviews, what to expect, and how to present your skills effectively to potential employers. It’s a valuable tool for anyone looking to excel in frontend development interviews.
JS Dates Are About to Be Fixed
Published: at 02:47 PMThe article explains how JavaScript's new Temporal API, specifically the Temporal.ZonedDateTime object, resolves longstanding issues with date and time handling. Traditional JavaScript Date objects lose critical context like time zones, leading to inaccuracies. Temporal fixes this by accurately representing dates with time zones, handling Daylight Saving Time, and providing reliable date comparisons and arithmetic. This new API simplifies global time consistency in modern web development.
