Using JS

Suppose i have alot a link like the below , it makes sense to add the attribute target="_blank" , but what if i have 10 o
f these kind of links , should i than add that attribute to the 10 links using JS ?? is that a better idea , i think that will help keep my HTML doc clean

good idea ? bad idea ?

<a href="abc.com" target="_blank"><i class="icon fa fa-google-plus"></i></a>
