OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:

.catch(failureCallback);
When a promise is created, it is neither in a success nor in a failure state. It is said to be pending. When
a promise returns, it is said to be resolved. A successfully resolved promise is said to be fulfilled. It
returns a value, which can be accessed by chaining a .then() block onto the end of the promise chain.
The callback function inside the .then() block will contain the promise's return value.
An unsuccessful resolved promise is said to be rejected. It returns a reason, an error message stating
why the promise was rejected. This reason can be accessed by chaining a .catch() block onto the end
of the promise chain.
Create a promises.js file and add the following code there:
