javascript - auto getter and setter in TypeScript - Stack Overflow

I've created this (sort of auto getter and setter) for javaScript but I don't know how to implement this in typeScript

I want to make an Object Oriented version of that if that's possible.

7 years later, TypeScript 4.9 now supports an uping ECMAScript feature called "auto accessors":

class MyClass {
  // This property 
  accessor myProperty: boolean = true
}

This does not provide access to the underlying private property, though. You can read up on how these work and why these were introduced here.

Currently, there is no good way to do this. I think you will just need to go the boilerplate-y way:

class Foo {
    private _bar: number;
    get bar() { return this._bar }
    set bar(bar: number) { this._bar = bar}
    // ...
}

If you wanted, you could use an editor snippet to make this a bit less of a pain.
