Does splicing wire weaken the integrity of the run

if running 12GA or 14GA house wire does splicing for necessary length dilute the strength or integrity of the circuit?

for example
i need to run 100' of wire for a chain of outlets and have 3 coils of wire,
one at 50' and two at 25'. is it OK to splice the lengths together rather than have to buy a new 100' roll?
if it is OK is there a maximum number of splices that can be on a run.
is this also OK for "home run type circuits" for washing machines, air conditioners etc?

of course the splices will be properly made and contained as per code

thanks for the advice

It's OK and it won't cause any voltage drop AFAIK.

To me though it would be a pain. You would need junction boxes with covers, strain relief, etc. If metal, each box would need a ground pigtailed to box.
Maybe you have easy access to install boxes and that's not so hard.

And the boxes must remain assessable, no burying in the wall.

There should be no performance issues if properly made.
