Local Storage

2 posts in this topic

Hello everyone,

I am a bit of a novice so this may be an easy question that I can't figure out, but I am trying to include local storage in the code below.  It is for a to do list but I want it to be able to store the changes made (entries added, removed, etc.).  I looked at the local storage examples but I just cant figure it out.  Any help would be appreciated.  Thanks!
