Raw is a lossless format editing and such does not degrade the image and can be undone. Jpg is not that way, there is only so much data and every edit changes and loses some of the data degrading the image. How bad it is damaged depends o. How much editing you do. You can edit your raw image archive it and also just make a jpg copy of it for emails and posting etc. some will tell you just openo g and closing a jpg cause it damage but I don't believe that and have seen no proof to support it,, manipulating a jpg does the damage. It is usually simple to make a jpg or tiff copy of a raw image. How depends on the software you use.
