7ad87515ad I'm not sure why plus here should be ignored. But OK. Biodegradable test code: 
auto answer = fast_float::parse_number_string<true>(
        f.data(), f.data() + f.size(),
        fast_float::parse_options(
            fast_float::chars_format::json |
            fast_float::chars_format::allow_leading_plus)); // should be ignored
    if (!answer.invalid) {
      std::cerr << "json parse accepted invalid json " << f << std::endl;
      return EXIT_FAILURE;
    }

c8894d3722 Cleanup for code near merged code: compiler generate much better code in any mode without manual unroling because it's less branching and also it's allow more inlining which is better.

3254622f74 Add chars_format::javascript_sloppy (Annex B NonOctalDecimalIntegerLiteral) 
chars_format::javascript follows the strict-mode grammar, which rejects
any leading zero. In sloppy mode, JavaScript also accepts a leading zero
when one of the digits is 8 or 9 ("08.5" is 8.5, Annex B's
NonOctalDecimalIntegerLiteral). A leading zero followed only by octal
digits is a LegacyOctalIntegerLiteral ("0775"), which is not a decimal
number: it is rejected with the new parse_error::legacy_octal_integer_part
so the caller can parse it in base 8.

javascript_sloppy sets one extra bit on top of javascript, and the check
lives inside the existing runtime JavaScript branch of
parse_number_string<false>, so the general path is unchanged. An
interleaved A/B with realbenchmark on canada.txt and mesh.txt (ASCII and
UTF-16, 32/64-bit) shows identical instructions per float and cycles
within noise.

Document both formats in the README.

f837a78057 Add chars_format::javascript (ECMAScript DecimalLiteral) 
The JSON format rejects leading zeros, which JavaScript also rejects,
but it further requires digits on both sides of the decimal point,
which JavaScript does not: ".5", "5." and "5.e3" are all valid
DecimalLiteral productions. Users lexing JavaScript therefore could not
use chars_format::json and had to re-check the integer span themselves
after a general-mode parse.

chars_format::javascript is general mode plus the leading-zero rule
(reported as leading_zeros_in_integer_part), with no_infnan. It is a
runtime check on the format, like fortran, so it reuses the existing
parse_number_string<false> instantiation. A leading minus sign is
accepted, and a leading plus sign with allow_leading_plus.
