Converting to an arrow function.

Hi,

I'm trying to convert this

$('li').on('click', function() {

 $(this).text("Clicked!");

});

To an arrow funcion. I can't seem to figure it out.
The closest i've got is :

$('li').on('click',() => {

$(this).text("Clicked!");

});

Which is probably allot further than I think..

Any assistance would be greatly appreciated.

Thanks

Actually the problem isn't the format conversion (which in itself is good), but the fact that your function uses "this" which is not defined in an arrow function like it is in a conventional one. Using "this" is one of several cases where arrow functions cannot be used.

Now what would work is if you also modify the function to accept and use the event object argument:

$('li').on('click', e => {
    $(e.target).text("Clicked!");
});

For a detailed explanation of the differences between arrow functions and conventional functions, see this MDN page on Arrow Functions.
