Even thought I have returned an error why then block is executed ?

Question

function func(state) {
return new Promise((resolve, reject) => {
if (state) {
resolve("promise is resolved");
} else {
reject("oops ! promise is rejected");
}
});
}

let promise = func(true);

promise.then((data) => {
console.log(data);
return new Error('test')
}).then((data) => {
console.log(`success ${data}`);
}).catch((err) => {
console.log(err);
})

Instead of returning an error, you should throw an error of course by using the throw keyword.
