Understanding core concepts like the DOM, async operations, and the web stack makes learning any framework straightforward. Framework debates create analysis paralysis that prevents developers from becoming employable. Focus on building strong foundations first, then choose a framework based on local job market demand rather than hype. 112 29 2. 2 [](https://daily.dev/posts/devs-waste-2-years-learning-javascript-javascript-javascriptframeworks-learningjavascript-fe3sgog2e "Devs waste 2 years learning JavaScript! #javascript #javascriptframeworks #learningjavascript") Video Stefan Mischook · 39w Devs waste 2 years learning JavaScript! #javascript #javascriptframeworks #learningjavascript Learning JavaScript frameworks like React before mastering core JavaScript fundamentals is a common mistake that wastes time. Understanding JavaScript's event-driven nature, including the event loop, closures, callbacks, and async patterns, is essential before diving into frameworks. Mastering JavaScript first makes learning React take weeks instead of months. 18 1 3. 3 [](https://daily.dev/posts/developers-write-only-10-of-the-deployed-code-in-2025--gjeiox3ri "Developers Write only 10% of the Deployed Code in 2025!") Video Stefan Mischook · 40w Developers Write only 10% of the Deployed Code in 2025! Developers today write only about 10% of the code they deploy, with the rest coming from libraries, frameworks, and increasingly AI tools. This trend has been ongoing since the 1990s, starting with the shift from manual memory management in C++ to automated memory management in Java and JavaScript. The evolution from writing low-level code to using pre-written libraries like React, and now AI-assisted development, represents a continuous pattern of abstraction that allows developers to focus on core application logic rather than boilerplate code. This shift enables faster development cycles, more sophisticated applications, and better code quality through rapid iteration. 12 3 [See all Stefan Mischook archives](/sources/stefanmischook/best-of) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@graph":[{"@type":"CollectionPage","@id":"https://daily.dev/sources/stefanmischook/best-of/2025/12#page","url":"https://daily.dev/sources/stefanmischook/best-of/2025/12","name":"Best Stefan Mischook Posts — December 2025","description":"The most upvoted Stefan Mischook posts from December 2025, curated by the daily.dev community.","isPartOf":{"@type":"WebSite","url":"https://daily.dev"}},{"@type":"ItemList","@id":"https://daily.dev/sources/stefanmischook/best-of/2025/12#items","numberOfItems":3,"itemListElement":[{"@type":"ListItem","position":1,"url":"https://daily.dev/posts/the-end-of-javascript-frameworks-juplzgul4","name":"The End of JavaScript Frameworks"},{"@type":"ListItem","position":2,"url":"https://daily.dev/posts/devs-waste-2-years-learning-javascript-javascript-javascriptframeworks-learningjavascript-fe3sgog2e","name":"Devs waste 2 years learning JavaScript! #javascript #javascriptframeworks #learningjavascript"},{"@type":"ListItem","position":3,"url":"https://daily.dev/posts/developers-write-only-10-of-the-deployed-code-in-2025--gjeiox3ri","name":"Developers Write only 10% of the Deployed Code in 2025!"}]},{"@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Sources","item":"https://daily.dev/sources"},{"@type":"ListItem","position":3,"name":"Stefan Mischook","item":"https://daily.dev/sources/stefanmischook"},{"@type":"ListItem","position":4,"name":"Best of","item":"https://daily.dev/sources/stefanmischook/best-of"},{"@type":"ListItem","position":5,"name":"December 2025"}]}]} ```
