Frequently asked
What is a Polyfill?›
A Polyfill is a piece of code that is used to provide modern functionality on older browsers that do not natively support it. It bridges the gap, allowing developers to use newer web features while maintaining backward compatibility with older browsers.
When should I use a Polyfill in my project?›
You should use a Polyfill in your project when you want to ensure that your web application works seamlessly across different browsers and versions, especially when making use of modern web features that are not supported by older browsers.
Can Polyfills cause performance issues in a web application?›
Although Polyfills help provide compatibility with older browsers, they can sometimes cause performance issues. Since they are essentially JavaScript code running in the browser, using a large number of Polyfills or large-sized Polyfills may slow down your application. To mitigate this, it's recommended to use only the necessary Polyfills and to load them conditionally, based on the user's browser.
How are Polyfills different from Shims?›
Both Polyfills and Shims serve the purpose of providing compatibility with older browsers, but they do so in slightly different ways. A Polyfill is used to replicate an entire API or functionality that is missing in the older browser, while a Shim typically modifies an existing API, often working around browser inconsistency or providing partial functionality of a missing API.
Are there any popular libraries that provide Polyfills?›
Yes, there are several popular libraries that provide Polyfills, such as core-js, polyfill.io, and Modernizr. These libraries detect browser support and only load the required Polyfills, making it easier to manage compatibility issues in your web applications.
