How do I break a promise chain?

Question

How should I stop the promise chain in this case? Execute the code of second then only when the condition in the first then is true.

var p = new Promise((res         


        

Answer 1

You could move the chain into the conditional branch:

p.then((res) => {
  if(true) {
    return Promise.resolve(res + 2).then((res) => {
      // executed only when the condition is true
    });
  } else {
    // do something 
    // chain ends here
  }
});
