JavaScript basics using parseint () to convert integers (005)

parseint () can parse an integer value in a string format, such as "32 days", to be resolved to a number of integers. The function also accepts the second argument, specifying the integer's binary (which, of course, should be in general decimal). A good habit is to always use this second parameter to prevent some unexpected bugs from appearing.

var month = "n", Year    = "The",    decimal = 10;month = parseint (month, decimal); year = parseint (year, decimal);

If the above code does not add the second argument to decimal, the string "09" is considered to be a 8-digit number, and 9 cannot appear in the 8 binary, the program will go wrong.
If the integer conversion always targets 10 data, you can also use the "+" operator or number () to complete the conversion:

+ ""/result is 8Number ("08")//8
