 Are you spending time trying to understand someone else's undocumented code? Have you been assigned to maintain an application written in a language unfamiliar to you? GitLab Duo Code Explanation helps you get up to speed so you can start being productive and ship code faster. Let's see how it works. Sasha, a software developer, has been tasked to maintain the application ProdManager that another programmer coded. This application is implemented in Java and Timelief that is using the ModelViewController design pattern. She navigates to where all the Java classes reside and opens the controller class AppController.java. Unfortunately, there aren't many comments in this class explaining what it is doing. She notices that the handler methods are straightforward except for method view home page. She also sees an if then else statement. To better understand, she highlights the entire if then else block and asks code explanation to explain this piece of code. Code Explanation returns a description and after reading it, Sasha realizes that this code block is part of a feature flag instrumentation for sorting the inventory by product in alphabetical order. Sasha then heads to the index.html-timelief file to see how this sorting is being displayed on the browser. She highlights a code segment where she thinks the inventory is being displayed and invokes code explanation, which confirms that this table iterates through the inventory to display each product's ID, name, brand, made in country, and price per row, and it also provides edit and delete links for each product. She now has a better understanding of what this application is doing and can get started maintaining it. Part Lab's Duo Code Explanation helps you get up to speed so you can ship code faster.
