Can a Script in JavaScript Determine the Time Zone Based on Area Code?
I possess the Area Codes of the User.
I extracted the details from this webpage and created a reference map:
const timeZoneMap = getTimeZoneMap()
// Check: https://stackoverflow.com/a/33561517/1762224
const phoneNumberPattern = /^[+]*[(]{0,1}\d{1,3}[)]{0,1}[-\s\./0-9]*$/g
console.log(timeZoneMap[extractAreaCode('(619) 555-5555')]) // California (PST)
function extractAreaCode(phoneNumber) {
if (phoneNumberPattern.test(phoneNumber)) {
return /\d{3}/.exec(phoneNumber)[0] // first three sequential
}
return null
}
function getTimeZoneMap() {
return {
"201" : { "timezone" : "EST", "state" : "New Jersey" },
"202" : { "timezone" : "EST", "state" : "District of Columbia" },
"203" : { "timezone" : "EST", "state" : "Connecticut" },
"205" : { "timezone" : "CST", "state" : "Alabama" },
... (Remaining content removed for brevity)
"980" : { "timezone" : "EST", "state" : "North Carolina" },
"984" : { "timezone" : "EST", "state" : "North Carolina" },
"985" : { "timezone" : "CST", "state" : "Louisiana" },
"989" : { "timezone" : "EST", "state" : "Michigan" }
}
