Combining the date from one source and the time from another source to create a unified date in Typescript

In my TypeScript code, I'm working with four fields of type Date:

StartDate
StartTime
EndDate
EndTime

My goal is to combine StartDate and StartTime into a single field called Start, as well as EndDate and EndTime into a field called End.

Despite attempting the following approach, it does not yield the desired result:

  start: new Date(e.startDate).setTime(e.startTime.getTime()),  
  end: new Date(e.endDate).setTime(e.endTime.getTime()),

Answer №1

Is this not sufficient?

// Setting up mock data for testing
const startDateTime: Date = new Date();
const startTime: Date = new Date();
const endDateTime: Date = new Date();
const endTime: Date = new Date();

// Merging date and time values
const mergedStartDateTime: Date = new Date(startDateTime);
mergedStartDateTime.setHours(startTime.getHours(), startTime.getMinutes(), startTime.getSeconds(), startTime.getMilliseconds());

const mergedEndDateTime: Date = new Date(endDateTime);
mergedEndDateTime.setHours(endTime.getHours(), endTime.getMinutes(), endTime.getSeconds(), endTime.getMilliseconds());
