Why we use salt bridge in daniel cell??​

Answer 1

The purpose of a salt bridge is not to move electrons from the electrolyte, rather it's to maintain charge balance because the electrons are moving from one-half cell to the other. The electrons flow from the anode to the cathode

Answer 2

I was learning about voltaic cells and came across salt bridges. If the purpose of the salt bridge is only to move electrons from an electrolyte solution to the other, then why can I not use a wire?

Also, will using NaCl instead of KNO3 in making the salt bridge have any effects on voltage/current output of the cell? why?

Plus if it matters, I'm using a Zinc-Copper voltaic cell with a tissue paper soaked in KNO3 as salt bridge
