What is the essence of BEM from Yandex?

Question

Web development

In terms of meaning, is it - jquery / gulp / jade - from Yandex?
I'm reading the documentation, but I can't figure out what the advantage of using this technology is. What is the profit from this?

Answer 1

In fact, all the collectors there are all secondary. The main thing is the principle of naming and using classes in HTML and CSS. This approach allows you to maintain a consistent approach to development even in the largest team. In addition, it allows you to exchange modules (html + css + js) between teams. For example, one team wrote, say, a sidebar. Another team can now easily and easily insert it into their project without having to worry about css style or class name conflicts.
