+The answer is: **no, it won't**:
+
+```js run
+new Promise(function(resolve, reject) {
+  setTimeout(() => {
+    throw new Error("Whoops!");
+  }, 1000);
+}).catch(alert);
+```
+
+As said in the chapter, there's an "implicit `try..catch`" around the function code. So all synchronous errors are handled.
+
+But here the error is generated not while the executor is running, but later. So the promise can't handle it.

+# Error in setTimeout
+
+How do you think, does the `.catch` trigger? Explain your answer?
+
+```js
+new Promise(function(resolve, reject) {
+  setTimeout(() => {
+    throw new Error("Whoops!");
+  }, 1000);
+}).catch(alert);
+```
