Hey Would something bad happen (or nothing), if I try to do JSON.parse(thing) and 'thing' is not an object or array ? Or does that change nothing ?

Could be anything else What i'm really trying to is

JSON.parse(window.LocalStorage.getItem('key')

JSON.parse(window.LocalStorage.getItem('key')

And I want to be sure how to catch error And if it always returns a string Documentation didn't help me figure it out Or I didn't understand

Wait, what If I stringify everything before set to Local Storage ? Then I would always deal with strings, right ? As such

window.localStorage.setItem('key', JSON.stringy(value)

window.localStorage.setItem('key', JSON.stringy(value)

It's purely theoritical, I'm not coding (Sorry I should have mentioned it) Well, thank you for your time I go with the approach of stringify-ing everything

either way localstorage can only store strings

I guess so, But documentation doesn't say what happens if I try

localStorage.setItem('key', true)

localStorage.setItem('key', true)

Would it become the string 'true' ? Or throw an Error

As a string ? So localStorage can store booleans ? 😮

It'll stringify it yes

Thanks for confirmation

As if you set .setItem('... ', {}); it'll just stringify it into [object Object]

window.localStorage.setItem('key', JSON.stringy(value)

window.localStorage.setItem('key', JSON.stringy(value)

I'll stick to this approach, stringying everything, I'll think about accuracy* later Thanks timo, thanks Eva

I thought JSON.stringify would be harmless on things that are already a string
