isn't localstorage as same as just a var

Question

is var name='myname'=localstorage.setItem('name','myname')
and when calling them we would use
name or localstorage.getItem('name')

Answer 1

when declaring var name; its value is saved in RAM memory its value will be lost when closing or restarting the program.

when you use localStorage.setItem ("key", "value") the data is stored locally.

the correct way is:

var name = localStorage.getItem ("name") || "noNamed";

function setName(newName){
localStorage.setItem("name", newName);
name = newName;
}

if(name == "noNamed"){
setName("Luis");
}

Now you can use var "name".

@maf, in this case is not necessary to use JSON.parse, only use it when store a json:

localStorage.set("user",
JSON.stringify({
name: "luis",
facoriteColor: "red"
})
);

Answer 2

The difference is that if u set an item through localStorage.setItem(), it would remain there, even if u refresh your page, so its like a local database. And you have to parse data into JSON, when getting the item, so, JSON.parse(localStorage.getItem("name"))
