Question

I do not want use each and every time parseInt('08', 10) for each string to integer conversion,

Can we modify parseInt method, so that i can use only parseInt('08') instead of parseInt('08', 10).?

Answer 1

Instead of modifying the built-in function parseInt, you can define your own function like this:

function prseInt(n)
{
    return parseInt(n, 10);
}

And replace all the occurences of parseInt(n, 10) you have used in your app with prseInt(n).

Fine, if you still wanna redefine, you can do this:

var origParseInt = parseInt;
parseInt = function(n) {
     return origParseInt(n, 10);
}

And it works!
