How to exclude a key from an interface in TypeScript

Question

In TypeScript, you can combine two interface types like this

interface Foo {
    var1: string
}

interface Bar {
    var2: string
}

type Combined = Foo & Ba         


        

Answer 1

In TypeScript 2.8 you can now do the following:

interface Foo {
    attribute1: string;
    optional2?: string;
    excludePlease: string;
}

// Typescript 3.5+ defines Omit for you.
// In earlier Typescript versions define Omit:
// type Omit = Pick>

// Use Omit to exclude one or more fields (use "excludePlease"|"field2"|"field3" etc to exclude multiple)
type Bar = Omit
const b: Bar = {
    attribute1: ''
};

So in relation to your question the following might be what you want:

export default function valueHOC
 (
  Comp: React.ComponentClass
 | React.StatelessComponent

): React.ComponentClass> {
  return class WrappedComponent extends React.Component, State> {
    render () {
      return (
        
      )
    }
}
