Promise creation and usage

This feature allows users to create new promises and handle their resolution or rejection. The code sample demonstrates how to create a new promise and use 'then' and 'catch' methods to handle its outcome.

const pinkiePromise = require('pinkie-promise');

const promise = new pinkiePromise(function(resolve, reject) {
  // Asynchronous operation here
  if (/* operation successful */) {
    resolve('Success!');
  } else {
    reject('Failure!');
  }
});

promise.then(function(value) {
  console.log(value); // 'Success!'
}).catch(function(reason) {
  console.log(reason); // 'Failure!'
});

Chaining promises

This feature demonstrates how promises can be chained to perform a sequence of asynchronous operations where each step waits for the previous one to complete.

const pinkiePromise = require('pinkie-promise');

pinkiePromise.resolve(1)
  .then(function(value) {
    return value + 1;
  })
  .then(function(value) {
    return value + 1;
  })
  .then(function(value) {
    console.log(value); // 3
  });
