+# What will setTimeout show?
+
+In the code below there's a `setTimeout` call scheduled, then a heavy calculation is run, that takes more than 100ms to finish.
+
+When the scheduled function will run?
+
+1. After the loop.
+2. Before the loop.
+3. In the beginning of the loop.
+
+
+What `alert` is going to show?
+
+```js
+let i = 0;
+
+setTimeout(() => alert(i), 100); // ?
+
+// assume that the time to execute this function is >100ms
+for(let j = 0; j < 100000000; j++) {
+  i++; 
+}
+```
