Function definition modeling Schrodinger's Cat.

schrodingersCat.js

const cat = {
  get state() {
    delete this.state;
    this.state = Math.random() >= 0.5 ? 'Alive' : 'Dead';
    return this.state;
  }
};

test.js

cat.state;  // "Quantum Wavefunction Collapse" - the function replaces itself with the result of its computation
cat.state;  // All future calls will return a static value and not a function
cat.state;
cat.state;
cat.state;
