Modify or delete strings using an array

Question

Modify or delete strings using an array

Currently, I am utilizing Google Scripts which means it is purely JavaScript.

The array that I am working with looks like this:

[Tue Dec 23 00:00:00 GMT+00:00 2014,
816.43,
Tue Jan 28 00:00:00 GMT+00:00 2014,
729.43]

My goal is to reformat the date in order to eliminate the time and GMT components so it would appear as follows:

[Tue Dec 23 2014,
816.43,
Tue Jan 28 2014,
729.43]

To achieve this, I have implemented a for loop and I am trying to utilize the .replace function to remove "00:00:00" and "GMT+00:00" from my array named 'data'

var arrayLength = data.length;
  for (var i = 0; i < arrayLength; i++) {
    var newData = data[i].replace("00:00:00", "");
  }

However, an error message is being displayed:

TypeError: Cannot find function replace in object Tue Dec 23 2014 00:00:00 GMT-0000 (GMT)

Answer №1

If you are facing the challenge of comparing two dates without taking the time into consideration, there are a few strategies you can utilize. One option is to create a function that removes the time component from a date by setting it to 00:00:00.0000. Another approach involves developing a function specifically for comparing two dates while disregarding the time-of-day details.

One solution is to implement a function that truncates a date to eliminate the time information entirely.
Alternatively, you could design a function tailored for comparing two dates with no regard for the time portion.

Your choice of method will ultimately depend on the requirements of your specific application.

In order to compare two dates without considering the time aspect:

function sameDay(d1, d2) {
  return d1.getFullYear() === d2.getFullYear() &&&
         d1.getMonth() === d2.getMonth() &&&
         d1.getDate() === d2.getDate();
}

To generate a new Date object with the time set precisely at midnight:

function midnightOf(d) {
  return new Date(d.getFullYear(), d.getMonth(), d.getDate());
}

While the code provided may not produce the exact output you desire, it may still be sufficient. Keep in mind that when dealing with object dumps, the results can vary:

for (let i = 0; i < data.length; i++) {
    if (data[i] instanceof Date) {
        data[i] = [data[i].getDay(), data[i].getMonth(), data[i].getYear()].join(' ');
    }
}

This snippet assumes you are working with Date objects and utilizing their respective methods. It converts the date objects to strings, though based on your description, it seems this may not be necessary.

Here's a possible solution:

 const arrayLength = data.length;
  for (let i = 0; i < arrayLength; i++) {
    const newData = data[i].toString().replace("00:00:00", "");
  }

It appears that the elements in the 'data' array are Date objects rather than strings.

If you are dealing with date strings and they have a consistent format, you can easily reformat them using the following methods:

var s = 'Tue Dec 23 00:00:00 GMT+00:00 2014';

var m = s.match(/^\w{3} \w{3} \d+|\d+$/g);
if (m) console.log(m.join(' '));

or

var n = s.split(' ');
console.log([n[0],n[1],n[2],n[5]].join(' '));

or

console.log(n[0] + ' ' + n[1] + ' ' + n[2] + ' ' + n[5]);

If you have Date objects and want to display them in the suggested format from the original post, you can create a simple function like this:

function formatDate(d) {
  var days = ['Sun','Mon','Tue','Wed','The','Fri','Sat'];
  var months = ['Jan','Feb','Mar','Apr','May','Jun',
                'Jul','Aug','Sep','Oct','Nov','Dec'];
  function z(n){return (n<10?'0':'') + n}
  return days[d.getDay()] + ' ' + months[d.getMonth()] + ' ' +
         z(d.getDate()) + ' ' + d.getFullYear();
}

console.log(formatDate(new Date(2014,11,2))); // Tue Dec 02 2014

Check out this method for standardizing the date array you're working with:

const datesCount = yourDates.length;
for (let j = 0; j < datesCount; j++) {
  yourDates[j].setHours(12,0,0,0); // adjusting to noon in case of DST transition
}
