westc / formatIntlDate.js
Last active April 20, 2024 03:48
A more intuitive version of a JS date formatter. This function leverages Intl.DateTimeFormat().
var formatIntlDate = (() => {
const codeToOpts = [...'Y=year M=month D=day H=hour h=hour m=minute s=second S:1 SS:2 SSS:3 MMM=month:short MMMM=month:long DDD=weekday:short DDDD=weekday:long A=hour:2D a=hour:2D Z:Offset ZZ:Offset ZZZ:Generic ZZZZ: J=year:numeric,month:2D,day:2D,hourCycle:h23,hour:2D,minute:2D,second:2D,fractionalSecondDigits:3,timeZoneName:longOffset'.replace(/(\w)=\w+(?= |$)/g, '$&:numeric $1$&:2D').replace(/hour/g, 'hourCycle:h23,$&').replace(/Z:/g, 'Z=timeZoneName:long').replace(/S:/g, 'S=fractionalSecondDigits:').replace(/2D/g, '2-digit').matchAll(/(\w+)=(\S+)/g)]
.reduce(
(codeToOpts, [_, code, strOpts]) => {
codeToOpts[code] = [...strOpts.matchAll(/(\w+):([^,]+)/g)].reduce(
(opts, [_, key, value]) => {
opts[key] = value;
return opts;
