Setting default values and specifying available values for a class property in TypeScript

I'm curious about how to set a default value for a class property, as well as define all available values at once. For example:

class MyClass{
  isActive = -1; //Setting default value
}

class MyClass{
  isActive: -1 | 0 | 1; //Defining all available values
}

And I would like to achieve something like this:
class MyClass{
  //isActive = -1 && isActive: -1 | 0 | 1
}

Answer №1

To implement this, you can utilize the following syntax:

class SomeClass {
    status: -1 | 0 | 1 = -1;
}

This is similar to how it's done with a regular variable declaration.

let status: -1 | 0 | 1 = -1;
