TypeScript introduces the classical type syntax you’re used to and the compiler produces the JavaScript that accomplishes the intent. Take the following JavaScript snippet: Copy var car; car....
and you're in. The package exposes a registerEventListeners() function which already has some event listeners and classes for you to just dive right in. Simply import the function into your project and use right away. Example:import {registerEventListeners} from "ije" //Always nice to ...
