What is the output of the following? “`js const p = Promise.reject(42); p.catch(v => v + 1).then(console.log); “`

Accepted Answer

The output of the code is 43. The Promise is rejected with the value 42, then the catch handler adds 1 to the value, resulting in 43, which is then logged to the console.
