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 VWO code fails to execute within a specified time, it stops and then loads the original content of the page.
