20,827 PointsRewrite JS using arrow function
Hello,
We have the following JS in this tutorial:
$(".loc").hover(
function(){
$(this).html("<strong>Location:</strong> Your house?!");
},
function(){
$(this).html("<strong>Location:</strong> Treehouse Adoption Center");
}
);
How should I rewrite this to make use of the arrow function? I've tried like this but it did not worked:
$(".loc").hover(
() => {
$(this).html("<strong>Location:</strong> Your house?!");
},
() => {
$(this).html("<strong>Location:</strong> Treehouse Adoption Center");
}
);

231,269 PointsArrow functions don't bind "this".
But you could explicitly use the event object to obtain the target:
$(".loc").hover(
(e) => {
$(e.target).html("<strong>Location:</strong> Your house?!");
},
(e) => {
$(e.target).html("<strong>Location:</strong> Treehouse Adoption Center");
}
);
See the Arrow Functions page on MDN for more info about how arrow functions differ from ordinary functions.
