What is different promise here
promise()
.then(
otherPromise()
)
.catch(error)
and here :
promise()
.then(() => {
otherPromise()
})
.catch(error)
Someone can help me with explain it
In the first example, you're passing the return value of calling otherPromise() to your then. In the second example you're passing a function which will call otherPromise() when the then is reached.
For example, lets assume otherPromise() just returns a string like this:
const otherPromise = () => 'Hello World';
In the first example you are passing the string 'Hello World' into your then, in the second you are passing a function in.
I suspect what you want to do is this:
promise()
.then(otherPromise)
.catch(error)
