javascript the difference between the number 01 and 1

I am writing a function that needs to be able to tell the difference between the numbers 01 and 1. I am doing a cubical search within a company directory and on the same floor there are cubicles numbered 01 and 1. When the cubical search returns 01 it automatically assumes the value is a 1 and not '01'.

Is there a method or something I could use to differentiate between '01' and '1'.

Thanks.

You will treat both inout as strings. Consider this:

var x = "01";
var y = "1";
var z;
if (x === y) {
    return true;
} else {
    return false;
}

Note there is a difference between == (value only) and === (value and type)

There is no difference between the numbers 01 and 1. They are absolutely identical. 

console.log(01 === 1);

There is a difference between the strings "01" and "1". If you need to distinguish between the values, then use strings, not numbers.

console.log("01" === "1");

These aren't really NUMBERS, they are CHARACTER STRINGS, whose characters all happen to be digits.

I presume that you are doing a "cubicle search" - a search for a cubicle (those little pens that companies keep people in), rather than some sort of mathematical search that involve cubes

Yes, string comparison.

When you treat these two values as strings then these two values will be different

var isEqual = '1' === '01'; // false

Only by converting them to numbers will they evaluate the same and be indistinguishable.
