Deep dives
The Necessity of JavaScript for Web Functionality
Most users do not turn off JavaScript while browsing the web, and many might not even know how to disable it. However, the discussion around whether a website should function without JavaScript is vital, especially for users on unreliable networks or those using older devices. Websites should load and present content in a readable format, even if JavaScript fails to load or executes incorrectly. This fundamental approach ensures that users can interact with the site without relying solely on JavaScript, providing a smoother experience across various conditions.
Progressive Enhancement as a Development Philosophy
Progressive enhancement emphasizes building websites with core content available to all users before adding enhancements that require JavaScript. This principle argues that basic functionalities like navigation and forms should work independently of JavaScript. Developers should use server-side rendering to ensure that content loads quickly and reliably, allowing for stronger user experiences even in environments where JavaScript may be limited. Ultimately, this strategy promotes accessibility and reliability in web design, allowing for a seamless interaction regardless of the user's situation.
Trends in Web Development and Standards
The shift back towards server-side rendering and reliance on web standards is gaining traction among developers, contrasting with an earlier focus on heavy client-side JavaScript. This shift reflects a growing awareness of the necessity for lightweight and adaptable web experiences that work across a spectrum of devices and networks. Emerging web technologies and APIs are enabling richer user interactions without excessive JavaScript, encouraging developers to rethink how they build applications. Ultimately, prioritizing web standards ensures not only functionality but also enhances user experience and engagement.
Scott and Wes debate whether your website really needs JavaScript to function. They explore the principles of web standards, progressive enhancement, and test popular websites like Shopify and Netflix to see how they perform without JavaScript.
