Setting Options in addEventListener
We can set options about addEventListener such as 'once', 'capture' or 'passive'.
I'm not going to write what the functions of the options are, but write how to apply them.
To apply them, we have to write something as the third argument.
Way 1: an Object
Below is the example.
Please be careful that IE does not support the way.
Way 2: a Boolean
If we just write a boolean, that is about 'capture' option.
Below in the example.
Luckily, IE supports the way.
