I want to check if localStorage is isset or not. e.g. i am creating sample localstrorage:
localStorage.setItem('TODO_LIST', 'value');
Now, i want to check on page load whether localStorage with name TODO_LIST
is isset or not, also if it is isset how to check whether it blank or not.

How about:
If (localStorage.getItem('TODO_LIST') && localStorage.getItem('TODO_LIST') !== '') {
// Do something when it's set and not empty
}
localStorage.getItem('TODO_LIST')
returns null
or falsy when it's not set.
localStorage.getItem('TODO_LIST') !== ''
returns true
if it's not empty.
