“What’s in a framework?”, one may ask, but what if we ask what is its purpose or why it was built, in the first place? Each front-end developer will, likely, start to consider, at some point, on a set of standards in the work he is doing – more exactly, on a set of rules to organize his work better.
Beside these strict settings he is willing to do, in order to build his own coding convention(1), he may be mainly concerned about the DRYed principle(2): Don’t Repeat Yourself that will give him a faster rate on writing code.
However, once a framework is learned, future projects can be faster and easier to complete;Wikipedia: Software framework rationale
