Document.addEventListener('DOMContentLoaded',( ) =>{

Question

Explain me this syntaxe plz ?

Answer 1

1.Document = who listens to event
2. addEventListener = method (in this case) of Document that adds a new reaction to an event.
The method expects two parameters
a) the Event (DOMContentLoaded)
b) a function

In this case the function is passed as a function without a name and without parameters.
( ) => {function body}

This kind of functions without name are arrow functions.

Answer 2

After Oma Falk 's explanation, I just want to add one thing that; DOMContentLoaded event is initialised when the entire HTML document is loaded.
Thanks.

Happy Coding 🤠
