In this post, we’ll explore these three methods to help you make informed decisions for your projects. Default Loading By default, JavaScript files are loaded synchronously when included in an HTML document. This means that the browser will pause parsing the HTML document to download and execute the…

Top 5 Game-Changing JavaScript Features in ECMAScript 2024: Boost Your Code Like Never Before!

stp2y0 CommentsNewscareer, coding, community, development, engineering, frontend, inclusive, javascript, learning, software

1. Top-Level await – Async Simplified! Gone are the days when async code required wrapping everything in functions. With top-level await, we can directly use await in modules without needing an async function wrapper. This feature is particularly handy for simplifying code and reducing boilerplate Before top-level await, fetching data required an async function: async function fetchData() { const response = await fetch('https://api.example.com/data'); const data = await response.json(); return data; } fetchData(); Enter fullscreen mode Exit fullscreen mode Now, with top-level await, we can call await at the root level: const response = await fetch('https://api.example.com/data'); const data = await response.json();…

Experiences and Caveats of Svelte 5 Migration

stp2y0 CommentsNewscoding, community, development, engineering, inclusive, javascript, software, svelte, sveltekit, tutorial

I have recently updated a rather complex web application. The application has features like auth, Stripe, i18n, dark/light mode, PWA, etc. Overall, it has around 30 pages and components, with almost no third-party npm packages. I would like to point out what I found quite challenging when migrating the app to Svelte 5. Auto-Migration Script Hammer The auto-migration script provided by Svelte can do the job for you with this "one-liner" command in the terminal npx sv migrate svelte-5 (after you do all the necessary updates and installs: "@sveltejs/vite-plugin-svelte": "^4.0.0" and "svelte": "^5"). But I do not recommend this "hammer"…
