Problems with parseint

Today, when I wrote JavaScript, I encountered a very depressing problem, that is, when I used parseint to convert to 10, all the correct results were obtained except for the error and 0 was returned. Later I checked the parseint Syntax:

Parseint (string, Radix );
Here, string is the string to be converted, and Radix is binary, octal, hexadecimal or decimal.
When radix is not specified by default, it is in hexadecimal format when 0x is switched. If 0 is switched and the second digit is not X, it is in octal format, (the error 0 is returned because there cannot be 8 or 9 in octal ).
Therefore, we should specify the carry-in system to avoid errors.
If we usually use decimal digits, we will use parseint ("08", 10 );
