Passing Parameters to Resolve Reject

Lecture 223:- Passing Parameters to Resolve Reject

To pass parameters to the resolve and reject methods of a promise, you can simply include the parameter as an argument when calling the method. For example:

javascriptCopy code

const promise = new Promise((resolve, reject) => {  // Do some async operation  if (/* operation successful */) {    resolve('Success message');  } else {    reject('Error message');  } }); promise  .then((message) => {    console.log(message); // logs 'Success message'  })  .catch((error) => {    console.error(error); // logs 'Error message'  });

In the above code, resolve('Success message') is called with the parameter 'Success message'. This parameter is then passed to the then() method as the message argument of the callback function. Similarly, the parameter 'Error message' is passed to the catch() method as the error argument of the callback function.
