Browser Support

Exadel Smart Library does not have dependencies but uses the following list of native browser features:

• ECMAScript 6 features
  • Array.from (no Iterable Objects support required)
  • Array.prototype.find
  • Array.prototype.findIndex
  • Array.prototype.include
  • Object.is
  • ES6 Promise
• Web API
  • Custom Events
  • Node.isConnected
  • Element.matches
  • Element.closest
  • Element.toggleAttribute
  • KeyboardEvent.key
  • IntersectionObserver
  • ResizeObserver
  • Custom Elements

All of them are fully supported by modern browsers such as Chrome, Firefox, Safari or Edge (>43).

In order to make ESL work in older browsers, you can use a "light" polyfills list of IntersectionObserver, ResizeObserver and Custom Elements (for older versions of Edge and Safari).

Or make the library work in IE11 or Edge (<14) by using the "full" polyfills list provided.

See more details on what polyfill approach might look like in the demo pages source code.

Also, ESL has built-in polyfills for some of DOM and ES6 features. They are available under polyfills directory.
