Conversion from ReactJS Javascript to TypeScript Component

Question

I am looking at an older React class that is written in JS. The class in JS references 'this.element' which is not something that intrinsically exists in a typescript class that extends React.Component. I'd love some direction on what 'this.element' is referencing and how to use it in the new TS Component model. TYIA

Answer 1

You need to define the property on the class:

 class SlideDownTransition extends React.Component {
    element: React.Component;

    /*...*/
 }
