Why are printed circuit boards used when constructing an electronic circuit?

It has a number of purposes. It provides a solid surface to mount the other components onto. It creates the connections in a neat and organized way that would not be possible if you just soldered each component to the next one. It also maintains the spacing to allow heat dissipation.
