I'm trying to create a date with the format 'mmddyyyy'. I've noticed I can pass a four digit string, but when I use the format above, it says invalid date. How can I go about this with pure js?
let dateString = '01012022'
let d = new Date(dateString)
maybe you want something like that
let dateString = '01012022'
let [match, dd, mm, yyyy] = dateString.match(/(\d{2})(\d{2})(\d{4})/)
// iso format
let d = new Date(`${yyyy}${mm}${dd}`)
Seems like you have to split your string into pieces then use common Date() constructor with separated day, month and year
//Your string with date
let dateString = '01012022';
//extracting 2 first numbers as m (month), 2 second as d (day) and the last 4 as y (year)
let {d,m,y} = /(?<m>\d{2})(?<d>\d{2})(?<y>\d{4})/.exec(dateString).groups;
//then create new date using constructor
let date = new Date(y,m,d);
