How to make a for loop var with a string that increments in js

Question

something like: for(var i="string 1"; i<10; i++){
i="string 2"
i="string 3"
}

and so on. Is it possible? Because I'm trying to store different things into the local storage using a for loop and i want each thing to start with a different key other than all being number indexes for easier extraction

It's totally unclear what your intention is -- neither the code nor the description help much. — Jon

for (var i = 1; i < 10; i++) {
    var string_to_store = "string " + i;
    /* store string_to_store to localStorage */
}

No it's absolutely fine, plus one.

That's rather obvious. It's down to the programmer to do something with the intermediate values of string_to_store.

It's totally wrong to place a variable and use it from outside the loop, as OP wanted to use localStorage...

@BhojendraNepal - The assumption is that the OP would do whatever he wanted to do inside the loop. Also, the OP's original piece of code would do nine values only ;)

Javascript supports + as a way of concatenating a string with something else. So you can do something along the lines of

for (var i = 1; i < 10; i++)
    var s = "string " + i;

s will have the value string 1, string 2, and so on.

Like this?

for(var i=0; i<10; i++){
 console.log("string " + i);//logs to the console: string 0, string 1,..string 9
}
