What are the best polyfills for modern web development?
Some of the best polyfills include Babel for ES6 features, Polyfill.io for various APIs, and core-js for ECMAScript features.
Can you explain what Babel does?
Babel is a JavaScript compiler that allows you to use next-generation JavaScript today by converting ES6+ code into a backwards-compatible version.
What is Polyfill.io and how does it work?
Polyfill.io is a service that detects the user's browser and serves only the necessary polyfills for that specific browser, optimizing performance.
Are there any performance concerns with using polyfills?
Yes, using too many polyfills can increase load times and affect performance, so it's important to only include what's necessary.
How do I decide which polyfills to use?
Evaluate your target browsers and features needed, then choose polyfills that cover those gaps without bloating your code.
