JavaScript:日期时间字符串格式的数字数组

var year = [1999,2000,2001,2002,2003];

let op = year.map(e => e+'-00-00')

console.log(op)

const year = [1999,2000,2001,2002,2003],
yearConvert = [...(function*(a){
  for(y of a) yield `${y}-00-00`;
})(year)];

console.log(yearConvert);

const year = [1999,2000,2001,2002,2003];
const dateString = year.map((ele) => `${ele}-00-00`);
console.log(dateString);

//Convert this array to Date Objects using Date constructor Date(year, monthIndex, day) month starts from '0'

const date = dateString.map((str) => { 
  const data = str.split('-');
  return new Date(data[0], data[1], data[2]+1);
});

console.log(date)

//To verify parse to date strings

const dateParsed = date.map((date) => date.toDateString());
console.log(dateParsed);
