Infinite loop from `unhandledRejection`

index.js

// Run this file to cause an `unhandledRejection` infinite loop
// > node index.js

// 2. Catch first unhandled promise rejection
// 4. Catch error inside unhandledRejection, causing an infinite loop
process.on('unhandledRejection', (reason, p) => {
  console.log('Unhandled Rejection at:', p, 'reason:', reason);
  
  new Promise(() => {
    const b = {};
    const a = {
      hello: 'yes',
      b
    };
    b.a = a;

    // 3. Fail with `Converting circular structure to JSON` error
    const output = JSON.stringify(a);
  
    console.log(output);
  });
});

// 1. Trigger first promise rejection
Promise.reject('Trigger first unhandled promise rejection');
