While RAW files are undoubtedly a far superior format to the .jpg because of all of the information you get from the file and the amount of changes you can make to the file, there are benefits to both image types. Shooting in .jpg can be helpful when you want to display an image right away or when you don't have post-processing software to edit your images. .Jpgs are also beneficial because they're much smaller files and so they don't take up nearly as much space on your computer or external hard drive. I often shoot in .JPG when I'm taking pictures on vacation and don't want to have to deal with a lot of editing or really large files. Shooting in RAW is best when you are in difficult or changing lighting and you want to have the ability to have enough information to edit exposure, white balance, etc. in post-processing. Shooting in RAW is also best really any time you want to have much more control over and flexibility with your image. You do need to keep in mind that if you shoot in RAW, you must do some post processing (even though it can be very minimal) because no post-processing is done for you in the camera. Another thing to keep in mind, you want to make sure that after you edit your file, you export it as a .jpg. You don't ever want to use RAW files for web or print use, they need to be edited and converted to a .jpg and then they're ready for web or print.
If you're unsure whether or not you want to shoot in RAW or .JPG, you can always shoot in both (as pictured below). This takes up more space but it gives you the option to work with both types of files! I did this a lot when I first started in photography and was still learning how to edit RAW files.
