2. Then this operation is not a crude search for keywords and replacement. In the above animation, you can see that there is a bar3 function call in the last line of code, but When we rename the bar function, bar3 is not affected.

In addition to renaming, another common refactoring operation is to extract a long piece of code and convert it into a separate function. In VS Code, we only need to select that piece of code, click the yellow light bulb icon, and then select the corresponding refactoring operation. This refactoring helps improve code readability and maintainability, and can also reduce duplicate code. The advantage of this refactoring operation is to extract a repetitive and difficult-to-understand code logic and convert it into a concise and independent function. This can improve the readability of the code, reduce repetitive code, and simplify the logic of the main function. Through refactoring operations, we can improve the quality of the code

4. The last thing to note is that not every language service supports refactoring operations. If you select a piece of code but don't see the yellow light bulb icon, it means that the language you are using may not support rapid refactoring.
