Pure JavaScript equivalent of jQuery's $( document ).on( 'pjax:complete', () => { … } );} );

Question

I have legacy code like this below. My goal replace jQuery in the project to pure JS .

...
$( document ).on( 'pjax:complete', () => {
    executeSomething();
} );
...

executeSomething() - accesses to API, executes some calculations based on it and renders the result on the active tab.

I wrapped this function to IIFE and it works

...
( function() {
    executeSomething();
})();
...

Question : Is this a similar implementation?

Dependencies

Answer 1

document.addEventListener('pjax:complete', () => {
  executeSomething();
});

An IIFE executes immediately. An event listener triggers the function only when the event occurs.
