I am coming from Java dev and new to javascript, can someone explains what is going on.
I am using localStorage to store my token in my browser.
localStorage.token = 'xxx'
When the users sign out, we remove the token, here is the code
localStorage.token = null
If we want to check wether the user is authenticated or not, we check the token
const isAuth = localStorage.token !== null
Here is the thing becomes weird to me. After I marked localStorage.token to null,
the result of localStorage.token !== null is still true !
I had done some investigation,
I logged the localStorage object and found out the token variable is "null" instead of null.
Here is my assumption.
When the browser needs to store the localStorage, it iterates inside the object fields, after finding the null object, it use toString to store the final form?
>Solution :
give a value or Sovrascrivi the one present in the localstorage with the function set item, like code below :
localStorage.setItem('token' , 'your token here ');
and for access the value :
localStorage.getItem('token')
window.console.log("token :",localStorage.getItem('token'))
