Transforming Date Formats in JavaScript Arrays

Understanding the Problem

In our example, we have an array called objproduct which consists of multiple objects. Each object contains a lastseen property that follows the format DD/MM/YYYY h:mm:ss a. Here's a sample representation of our array:

2. Looping through the Array

We'll use the forEach method to iterate through each object in the objproduct array. Here’s how to properly change the value of each lastseen property:

3. Explanation of the Code

Let's break down the code above into digestible pieces:

forEach: This method allows us to execute a provided function once for each array element. In our case, it processes each object in objproduct.

moment(): This function creates a moment object from the lastseen date string in the original format.

format(): Converts the moment object into a string in the specified new format.

4. Final Output

After running the loop with the provided code, all lastseen dates will be updated to the desired format. You can print the resulting array to verify the changes:
