Choosing VWO Asynchronous code over Synchronous code has the following advantages:
- Asynchronous code loads in parallel with your website, thereby reducing the page load time during a test. On the other hand, Synchronous code executes each statement sequentially and does not load even if a single statement in the code fails to execute.
- With Asynchronous code, you can customize time-out parameters for VWO code to execute and make sure that your visitors do not experience any inconsistent behavior while using the website. If the VWO code fails to execute within a specified time, it stops and then loads the original content of the page.
