Parseint()

Question

a='2';
c=parseint(a,10);
document.write(c);
what output c ?

Answer 1

10 is to indicate what base is the value, in this case it is decimal number. Other example is 16, this is to indicate that the value would be in hexadecimal.

Answer 2

There is an error because 'parseint' is not defined ( you must write 'parseInt' -- JS, like almost languages, is case sensitive ^^ )...
But missing 'var' keyword raise an error only in JS 'strict' mode... what you should explicitly activate ;)

Answer 3

Error no output.
Unless the code is:
var a = '2';
var c = parseInt(a,10);
document.write(c);

Then the output is 2.
