BEM usefulness?

Hi,

After I watched that video I left it a little confused as to what was a "best practice" but everything else you can research and read up on for me seems to suggest this in a few more words than i will use to keep things simpler.

If you work as a team with, css developers, javascript developers and others alike, It is the teams responsibility to have a set naming convention in place, be that BEM or there own they prefer.

If you are a freelancer, you could name things however you like, BUT having a solid naming convention in place will pay dividends in the future especially if you expand and look to involve other on a project.

If I just give you a snippet of my Sass naming conventions:

//* VARS 
//*******************************************
$base-font-size
$large-font-size

$brand-header-color
$brand-hover-header-color
/*Nothing special but keeping it simple means to me a lack of available missed dashes or underscores*/

//* FUNCTIONS
//*******************************************
@function my_function($n) {
  @return $n * 2;
}
/*This is how I name my PHP / WordPress functions so it keeps the same feel for me*/

//* MIXINS
//*******************************************
@mixin myMixin($w, $h) {
  width: $w;
  height: $h;
}
/*I chose camelCase for its tight feel in the document and it felt a good change up*/

Nothing special but for me the convention matches that of what i use in other langs, I name my HTML classes and id's with the same convention as the Sass vars.

My comments all always in CAPS in SCSS or CSS and in Initial Caps in HTML. I thought id just give you an insight into mine to possibly spark some ideas of your own :)

In my opinion BEM is great in theory, my reason for disliking in practice is the over use of underscores making you stretch around the keyboard to often with the need for double keying, but that is simply my option im all about comfort and efficiency.

I hope this helps in some way :)
