What is the output of following code?
const p1 = new Promise((resolve, reject) => {
resolve();
resolve();
resolve();
});
p1.then(() => {
console.log("Resolved");
});
----o----
The output is:
"Resolved"
Even though resolve()
is called 3 times, the code will be resolved only once. That is how promises work.
Same is the case with reject()
. Even if the code is rejected multiple times, .catch()
will be called only once.
