interface A{
a: string;
b: string;
c: string;
// potentially more properties
}
interface B{
[K in keyof A]: Boolean;
}
What could be the issue with this code? My goal is to generate a similar structure programmatically:
interface B{
x: Boolean;
y: Boolean;
z: Boolean;
// perhaps additional properties later on
}
Instead of using Boolean, it's better to use boolean.
In addition, mapped types are only compatible with type and not interface. There is minimal distinction between the two, so this code should suffice:
type Bar = {
[key in keyof A]: boolean
}
Furthermore, you can rewrite this mapped type using the predefined mapped type Record:
type Bar = Record<keyof A, boolean>
Consider the following approach:
interface ExampleInterface{
property1: string;
property2: string;
property3: string;
// additional properties can be added later
}
type ExampleType = {
[key in keyof ExampleInterface]: boolean
}
interface AnotherInterface extends ExampleType { }
