JS Error Fixes for latest AAMVAtoJSON.js File

[christopherlrogers]

The following corrects JS Validation issues found in the last commit where multiple semicolons were missing especially on lines 25, 57, 59 cause Line Break Errors.

This version now validates to the ES6 requirements and fixes the Line Break Errors found.

function AAMVAtoJSON(data, options = { format: 'string' }) {
// Detect AAMVA header:
// 1. First two characters: "@\n"
// 2. Third character should be 0x1e but we ignore because of South Carolina 0x1c edge condition
// 3. Next 5 characters either "ANSI " or "AAMVA"
// 4. Next 12 characters: IIN, AAMVAVersion, JurisdictionVersion, numberOfEntries
let [header, AAMVAType, IIN, AAMVAVersion, jurisdictionVersion, numberOfEntries]
= data.match(/^@\n.\r(ANSI |AAMVA)(\d{6})(\d{2})(\d{2})(\d{2})?/) || [];
AAMVAVersion = +AAMVAVersion;
jurisdictionVersion = +jurisdictionVersion;

const obj = {
header: {
AAMVAType,
IIN,
AAMVAVersion,
jurisdictionVersion,
},
};

for (let i = 0; !numberOfEntries || i < numberOfEntries; i++) {
const entryOffset = header.length + i * 10;
let [, subfileType, offset, length]
= data.substring(entryOffset, entryOffset + 10).match(/(.{2})(\d{4})(\d{4})/) || [];
if (!subfileType) break;
offset = +offset;
length = +length;
if (i === 0) obj.files = [];
obj.files.push(subfileType);
obj[subfileType] = data.substring(offset + 2, offset + length).trim().split(/\n\r?/).reduce((p, c) => {
p[c.substring(0, 3)] = c.substring(3);
return p;
}, { });
}

// Convert date string (in local timezone) into Javascript UTC time
function convertAAMVADate(str, country) {
function convertMMDDCCYY(str) {
const [__str, month, day, year] = str.match(/(\d{2})(\d{2})(\d{4})/) || [];
if (!__str) return null;
return new Date(year, month - 1, day).getTime();
}
function convertCCYYMMDD(str) {
const [__str, year, month, day] = str.match(/(\d{4})(\d{2})(\d{2})/) || [];
if (!__str) return null;
return new Date(year, month - 1, day).getTime();
}
switch (country) {
case 'USA': return convertMMDDCCYY(str);
case 'CAN': return convertCCYYMMDD(str);
default: return convertCCYYMMDD(str);
}
}

if (obj.DL) {
for (const k of ['DBA', 'DBB', 'DBD', 'DDB', 'DDC', 'DDH', 'DDI', 'DDJ']) {
if (!obj.DL[k]) continue;
const t = convertAAMVADate(obj.DL[k], obj.DL.DCG);
if (!t) continue;
obj.DL[k] = t;
}
}

if (options && options.format === 'string') {
return JSON.stringify(obj);
}

return obj;
}

@christopherlrogers I put the semicolons back to address the issues raised by https://jshint.com.

I kept the ES6 version in the master branch, but, you can now try the non ES6 version in the non-es6 branch.
