Topic: Why in js .concat([...this.options. ?
Hello,
I came across an MDBootstrap error on Internet Explorer on the file mdb.min.js. This file contains the following code:
var fas = $nativeSelectChild.data('fas') ? " ") : ''; var far = $nativeSelectChild.data('far') ? " ") : ''; var fab = $nativeSelectChild.data('fab') ? " ") : '';
Why do you use .concat([...this.options ?
Correcting as follows .concat([this.options this works on IE 11.
Thank you,
Regards,
Hi there,
We use it, because there's a possibility that this.options could be an array. This syntax is called spread operator and is very helpful in such situations.
Best regards
