Understanding the Problem: Extracting a Date in Javascript

When working with APIs and JSON data, you might often find yourself needing to extract and format dates. A common situation arises when fetching data that includes timestamps in standard ISO format. For example, consider the object returned from an Axios call that includes a key, meeting_start_time.

You might face the challenge of converting the ISO date string, such as "2022-07-09T02:01:19", into a more readable format, like "MM/DD/YYYY". The need to display this information in a friendly format often arises when rendering components, such as a calendar.

In this guide, we’ll walk through a straightforward solution to extract the start time of a meeting from our object and convert it into a human-readable date format.

The JSON Object Breakdown

Here's an example JSON object returned from an Axios call:

Our goal is to extract the meeting_start_time from this object and format it into a string of MM/DD/YYYY.

Steps to Solve the Problem

To achieve our goal, we can utilize two powerful JavaScript methods—Date constructor and toLocaleString. Here's how we can do it step-by-step:

Step 1: Parse the Date

Use the JavaScript Date constructor to convert the ISO date string into a Date object. This allows us to manipulate the date easily.

Step 2: Convert to Locale String Format

Utilize the toLocaleString method to convert the Date object into a locale-specific string which includes both the date and time.

Step 3: Format the Output

Since we only need the date in MM/DD/YYYY format, we can split the resulting string by a comma and take the first part, which represents the date.

Example Code Implementation

Here's how you can implement the steps we outlined above in JavaScript:

Conclusion

With this straightforward approach, you can extract the meeting_start_time from your JSON object and format it in a way that is easier to read and display. This method is efficient and does not require complex regular expressions, thereby simplifying your code.

Feel free to use this solution in your projects whenever you need to extract and format dates from strings in Javascript!
