Can you change gears in manual transmission without stepping on the clutch ?

My friend has a honda civic manual and having a good time in drag racing and when in a quartermile sprint you should not step on the clutch instead when you are in 1st gear the engine rev must be in red line and just pull out the gear without stepping on the clutch.
Update: He just show me but is it good or bad for the transmission ?
