how to make 2 pages of javascript codes go into 1 page

To combine two pages of JavaScript code into one page, you can simply copy and paste the code from one page into the other. Here are some steps you can take to ensure that the combined code runs smoothly:

1. Make sure to check for any duplicate variable or function names between the two pages. If there are duplicates, make sure to rename them to avoid conflicts.

2. Check for any global variables or functions that need to be moved or adjusted. Make sure that all variables and functions are properly scoped and defined.

3. Ensure that any external dependencies are included in the combined code. This includes any external libraries or scripts that the original pages were using.

4. Test the combined code to make sure it runs as expected. Check for any errors or bugs that may have been introduced during the combination process.

By following these steps, you should be able to successfully combine two pages of JavaScript code into one page.
