Append to object

by Andrey Krasovsky @bre30kra69cs

   

Implement a type that adds a new field to the interface. The type takes the three arguments. The output should be an object with the new field.

For example

type Test = { id: '1' }
type Result = AppendToObject<Test, 'value', 4> // expected to be { id: '1', value: 4 }
