I am new to Javascript and trying to understand how Promise really works. I understand basics of how chaining works in Promise.

Is version 1 equivalent to version 2.

How does version 2 works? Since “catch” is chained to “then”, does “then” returns a “Promise”?

version 1:

const pr = new Promise((resolve, reject) => {
  const test = false;

  if (test) {
    resolve("Promise resolved");
  } else {
    reject("Promise Rejected");
  }
});

pr.then((resolve) => console.log(resolve));

pr.catch((error) => console.log(error));

version 2:

const pr = new Promise((resolve, reject) => {
  const test = false;

  if (test) {
    resolve("Promise resolved");
  } else {
    reject("Promise Rejected");
  }
});

pr.then((resolve) => console.log(resolve))
.catch((error) => console.log(error));
