+# Rewrite setTimeout with setInterval
+
+Rewrite the split counting function from setTimeout to setInterval:
+
+```js run
+let i = 0;
+
+let start = Date.now();
+
+function count() {
+
+  if (i == 1000000000) {
+    alert("Done in " + (Date.now() - start) + 'ms');
+  } else {
+    setTimeout(count, 0);
+  }
+
+  for(let j = 0; j < 1000000; j++) {
+    i++;
+  }
+
+}
+
+count();
+```
