This package implements @cached_property for Node,
inspired by Python 3.8 [functools.cached_property].
The package also includes TypeScript typing.

``shell`
yarn add cached_property
`ts`
import { cached_property } from "cached_property";
`ts
class CachedPropertyTest {
private readonly multiplier: number;
constructor() {
this.multiplier = -Math.random() * 1000;
}
@cached_property
public get seconds(): number {
return Math.random() * this.multiplier;
}
@cached_property
public get more_seconds(): number {
return Math.random() * this.multiplier;
}
}
const t1 = new CachedPropertyTest();
const t2 = new CachedPropertyTest();
console.log('t1', t1);
console.log('t2', t2);
console.log(t1.seconds);
console.log(t1.seconds);
console.log(t1.more_seconds);
console.log(t2.seconds);
console.log(t2.seconds);
console.log(t2.more_seconds);
`
prints:
`
t1 CachedPropertyTest { multiplier: -744.8363910755569 }
t2 CachedPropertyTest { multiplier: -740.5825190870856 }
