The big idea
localStorage lets your webpage remember things even after the user closes the tab. No server needed. AI can show you the small pile of code that makes it work and warn you about the gotchas.
Some examples
- Ask AI to save a dark-mode toggle to localStorage
- Ask AI why localStorage broke when you tried to store an object
- Ask AI for the JSON.stringify trick
- Ask AI when localStorage is the wrong choice
Try it!
Build a one-page note app. Ask AI to add localStorage so notes survive a refresh. Test it by closing the tab and reopening.
