In 2012 she presented BEM as a way to modularize the development of pages. By breaking things into Blocks, being able to break those into Elements, and then use Modifiers on them, we get a neat TLA and a methodology where each part can advance rapidly and independently, instead of having to get the CSS done, and then have everyone wait for the Javascript guy, only to have the project return to the HTML guy and have to run through the whole development cycle again.
This time Varya was showing what a great difference BEM makes to the process of development. Building independent interface components, rather than separating the HTML, CSS and Javascript development, we get unified terms (the frontend dialect) for all the project guys, reusable code and scalable teams More info at: https://fronteers.nl/congres/2013/jam-session/divide-impera
