JavaScript's ECMAScript 2025 introduces new iterator methods and improved set functionalities, enhancing performance and usability for developers.
The dynamic type hints feature in Module Federation 2.0 dramatically streamlines the development process by automatically generating and loading types from remote modules, eliminating the need for shared type packages.
One of the most significant changes is the move to integrate CSS module support directly into webpack's core. Currently available behind the experimental.css option, this feature eliminates the need for mini-css-extract-plugin. The team expects to complete integration into core around early 2026, with the feature remaining experimental until webpack 6, at which point plugin-based CSS handling will no longer be necessary.
Modern web applications are no longer just "sites." They are long-lived, highly interactive systems that span multiple runtimes, global content delivery networks, edge caches, background workers, and increasingly complex data pipelines. They are expected to load instantly, remain responsive under poor network conditions, and degrade gracefully when something goes wrong.
When applications grow, state becomes messy, components break, and small changes ripple into unexpected bugs. This is where many learners realize that knowing React syntax is not the same as knowing how React applications are built.
By how much? Well, that would depend on the value of the <length> argument provided. Thomas Walichiewicz, who proposed :near(), suggests that it works like this: button:near(3rem) { /* Pointer is within 3rem of the button */ } For those wondering, yes, we can use the Pythagorean theorem to measure the straight-line distance between two elements using JavaScript ("Euclidean distance" is the mathematical term), so I imagine that's what would be used behind the scenes here.
Today's browsers can handle most of the problems that frontend frameworks were originally created to solve. Web Components provide encapsulation, ES modules manage dependencies, modern CSS features like Grid and container queries enable complex layouts, and the Fetch API covers network requests. Despite this, developers still default to React, Angular, Vue, or another JavaScript framework to address problems the browser already handles natively. That default often trades real user costs -page weight, performance, and SEO - for developer convenience.
Waku, a minimal React framework has released version 1.0 alpha, marking its public API surface area as stable as the project shifts focus towards bug fixes and compatibility improvements. Waku 1.0 alpha represents a significant milestone for the lightweight framework, which has been in development for nearly three years. The release stabilises the framework's public APIs and signals a transition from feature development to refinement and stability.
Angular is a cohesive, all-in-one reactive framework for web development. It is one of the larger reactive frameworks, focused on being a single architectural system that handles all your web development needs under one idiom. While Angular was long criticized for being heavyweight as compared to React, many of those issues were addressed in Angular 19. Modern Angular is built around the Signals API and minimal formality, while still delivering a one-stop-shop that includes dependency injection and integrated routing.
Teams often use customer and user interchangeably until it breaks alignment. Here's how separating the two clarifies research, prioritization, and messaging across B2C, B2B, and B2B2C products.
Can you formulate the css code to apply the glassmorphism (GM) effect b/g to the tasks below: Glassmorphism code snippet background: rgba(255, 255, 255, 0.2); backdrop-filter: blur(5px); border: 1px solid rgba(255, 255, 255, 0.1); 1.1 Apply the GM effect to the Share B/G, Gallery B/G & Vid B/G icons during onmouseout. 1.2 Apply the GM effect to the Social icons pop-up panel B/G during onmousehover on the Share icon.
The web is full of AI assistants that appear to understand application UIs, user data, and intent. In practice, however, most of these systems operate outside the application itself. When you try to build one from scratch, you quickly run into a core limitation: large language models have no native understanding of your React state, component hierarchy, or business logic.

Welcome to The CSS Selection 2026! In this article we're having a look at how CSS is used at scale on over 100,000 websites. We'll look at what things are common on most websites and discover interesting outliers. This is the first edition of what I hope to be many, so this is meant as a baseline for future editions, setting up the first numbers to compare with in coming years.
