break in a case with return.. and for default

Question

My OCD makes me add \"break\" when writing case statements, even if they will not be executed. Consider the following code example:

switch(option) {
    cas         


        

Answer 1

Neither break does anything for you, but neither does harm.

Personally, I usually leave them out if I have a return - but I also try to avoid having multiple return points in a function if possible.

However, I do think the break in the default: case is good - for one reason: If you were to leave it out, and somebody added a new case after default:, the behavior would be different if they "forget" to add in a break.
