What is the point of double clutching?

The purpose of the double-clutch technique is to aid in matching the rotational speed of the input shaft being driven by the engine to the rotational speed of the gear the driver wishes to select.

Is it good to double clutch?

A: If you drive a modern manual car, you do not need to double clutch. It is no longer inherently good nor bad, though some people would say it makes shifting more deliberate, which extends life.
