+# Using async/await in JavaScript in Selenium
+
+Thanks [Stuart Langridge](https://twitter.com/sil/status/1312137808111304704) for showing me how to do this:
+
+```python
+from selenium import webdriver
+
+chromedriver_path = "/Users/simon/bin/chromedriver"
+driver = webdriver.Chrome(executable_path=chromedriver_path)
+
+script = """
+done = arguments[arguments.length-1];
+a1 = async () => {
+    return 42
+};
+a2 = async() => {
+    return await a1()+1
+};
+a2().then(done);
+"""
+output = driver.execute_async_script(script)
+# output is now the Python integer 43
+```
