I'm wondering why on so many circuit designs, particularly ones involving ICs, there is a point, often right before the connection to the supply or drain where it branches to a capacitor, often 100nF or so, which connects to ground. Is this like a cushion for changes in current?
here is an example:

The odd thing is that looking at motor control designs, I have seen many that are almost identicle except for including or excluding these capacitors. And many chips have a similar branch to ground on their connection diagrams. So what does it do?
