How can I convert a string to a date object in JavaScript with a specific format?
Gable E

To convert a string to a date object in JavaScript with a specific format, you can use theDate constructor and a combination of string manipulation and built-in date methods. Here's a step-by-step guide on how you can achieve this: 1. Define the input string and the desired format:

1
2
3
4

   const dateString = '2023-05-18';
   const format = 'YYYY-MM-DD';

2. Create a function that maps the format placeholders to their corresponding values:

1
2
3
4
5
6
7
8
9
10
11
12

   function getDateValues(dateString, format) {
     const dateParts = dateString.split('-');
     const formatParts = format.split('-');

     return formatParts.reduce((values, part, index) => {
       const key = part.charAt(0);
       values[key] = parseInt(dateParts[index]);
       return values;
     }, {});
   }

3. Use thegetDateValues() function to obtain an object with the year, month, and day values:

1
2
3

   const dateValues = getDateValues(dateString, format);

4. Construct the date object using the obtained values:

1
2
3

   const dateObject = new Date(dateValues.YYYY, dateValues.MM - 1, dateValues.DD);

Now,dateObject will hold the date object corresponding to the input string and format. Note: The format placeholder letters used in thegetDateValues() function (e.g., 'YYYY', 'MM', 'DD') can be customized to match your desired format. Make sure to adjust the function accordingly. Here's an example of the complete code:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19

function getDateValues(dateString, format) {
  const dateParts = dateString.split('-');
  const formatParts = format.split('-');

  return formatParts.reduce((values, part, index) => {
    const key = part.charAt(0);
    values[key] = parseInt(dateParts[index]);
    return values;
  }, {});
}

const dateString = '2023-05-18';
const format = 'YYYY-MM-DD';

const dateValues = getDateValues(dateString, format);
const dateObject = new Date(dateValues.YYYY, dateValues.MM - 1, dateValues.DD);

console.log(dateObject);

In the example above, the input string is'2023-05-18', and the format is'YYYY-MM-DD'. The resulting date object corresponds to May 18, 2023. Adjust the code according to your specific format requirements.
