Issue with Dates in Typescript array elements

When attempting to compare different Date elements in my code, I encountered an issue. I have two date elements representing date formats but am unable to compare them because I keep receiving the error message "core.js:6237 ERROR TypeError: newticketList.createdAt.toDateString is not a function". This happens with other functions like getDate or getMonth as well. I've researched and discovered that it may not be recognized as a Date format. How can I work around this?

 ticketList: Array<Ticket>;
let dateTime = new Date()

(...)

this.ticketList = this.ticketList.filter(
      newticketList => (newticketList.createdAt.toDateString() != dateTime.toDateString()))
angulartypescriptdateangular-date-format

Answer №1

createdAt does not have a function named toDateString

this.ticketList.map(
  newticketList => console.log(newticketList.createdAt));

Observe the output

Answer №2

Finally completed it. even though both variables were declared as Date objects, they were mistakenly treated as Strings The fix was to replace:

newdataList => 
        (newdataList.updatedAt.toDateString() != timestamp.toDateString()))

With this:

newdataList => 
        (new Date(newdataList.updatedAt).toDateString() != timestamp.toDateString()))
