Javascript regexp backslash removal query

Question

I was looking at the responses to the question at Removing backslashes from strings in javascript and found that both the responses work,

string.replace(/\\\//g, "/");

and

str = str.replace(/\\/g, '');

Could someone please explain the difference between these two and which would be a better choice?

The first one unescapes forward slashes specifically (ie replacing \/ with /)

The second just removes all backslashes.

is that necessary (replacing the forward slashes I mean)?

The second solution str = str.replace(/\\/g, ''); is wrong, because it will remove single \ from the string.

Actually it removes all backslashes from the string. Could you please give the example you tried where it did not?

The question was to remove \\ (consecutive backslashes) not \ (single backslash).
