title: Effect changes to JavaScript code are influential anywhere in terms of application performance?
body: <p>I want to ask if I change a few lines of JavaScript function code, rename the function, change position to the last of the file, or make another change. To which parts of the changes do I make to the application I made the change?</p>
  
  <p>For example, I changed the JavaScript code on 1 file to display the main page. Whether the change affects other pages in terms of application performance or other page access speeds (in this case, let's say the user has no interruption in internet speed)?</p>
  
  <p>I am very grateful for every comment you give.</p>
