Question

Answer 1

if (window.performance) {
  console.info("window.performance works fine on this browser");
}
  if (performance.navigation.type == 1) {
    console.info( "This page is reloaded" );
  } else {
    console.info( "This page is not reloaded");
  }

Answer 2

• For handling refresh you can use the window.onbeforeunload and write a function.
• For new tab you can use the window.onblur and write a function.

Both these hooks are compatible across all the major browsers Chrome, Firefox, Safari, Edge and IE.
