Generics in Classes
Now let's take a look at classes.
This class component has a
props attribute, which is currently being typed as
Inside the constructor, you have to pass it
props which are then assigned to
this.props. There is a
getProps function that will return the props.
0:00 Let's look at classes next. We have a Component class here that has a props attribute which is currently being typed as unknown. Inside the constructor, you have to pass it props. It then assigns props that you pass in, and it has a function that returns getProps.
0:17 Currently, we have a component that we're passing in a 1, b 2, c 3. We're getting this Component, and it's a class, basically. That result, though, is typed as unknown, and we're expecting the result to equal the type of a number, b number, and c number.
0:33 Your job is to figure out when we call this component, we want to technically be able to pass any shape of props, which sounds like a generic, and your job is to try and work out how to make props generic.
