why parseInt('08') is giving 0, whereas parseInt('07') is giving 7 [duplicate]

Answer 1

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');
