why parseInt(’08′) is giving 0, whereas parseInt(’07′) is giving 7

I am working on javascript, and I seem to find this strange, that the javascript function parseInt(’08′) is returning 0 and parseInt(’07′) is returning 7.

this behavior seems to be there in Firefox.

parseInt(’08′) is returning 8 in IE, but 0 in Firefox..

Why? I want parseInt(’08′) to return 8, as expected and getting in IE.

Yeah, I came across this one before. It is really odd because some browsers interpret this as you wanting to parse it in base 8. Consider the following article:

basically, you have to tell the parser to use base 10 numbers:

parseInt('08', '10');
