An example of an AI chatbot conversation about core-js polyfills and their functionality.
What are core-js polyfills and how do they work?
Core-js polyfills are JavaScript libraries that provide support for modern features in older environments. They allow developers to use new JavaScript functionalities without worrying about browser compatibility.
Can you give me an example of a feature that core-js polyfills support?
Sure! One example is the Promise object. Core-js polyfills allow you to use Promises in environments that do not natively support them.
How do I include core-js in my project?
You can include core-js in your project by installing it via npm with the command npm install core-js, and then importing the specific polyfills you need.
Are there any performance concerns when using polyfills?
Yes, using polyfills can increase the size of your JavaScript bundle, which may affect performance. It's best to only include the polyfills you need.
