Bipolar Junction Transistors (BJTs) are widely used in modern digital electronics because they consume a negligible amount of current during transitions.

Bipolar transistors switch by controlling a current into the base to permit a much larger current from collector to emitter. To turn on you must drive base current; to turn off you remove it. That base current flows during switching and contributes to power dissipation, so the current isn’t negligible during transitions. Modern digital logic favors MOSFETs because their gates draw almost no steady current, and the switching energy mainly comes from charging and discharging load capacitances rather than base drive. So the statement is false.
