What is the method to access the information within the observer?

When I receive the data from the observer in the console, here is what I see:

However, I am only interested in extracting this specific data from each item on the list:

To extract the observer, all I need to do is:

this.item.specialties

Is there a way for me to create an array containing only the ids? Thank you in advance.

Answer №1

Utilize the Array.prototype.map() method to transform the array into a new array.

If this.item.specialties represents an array of objects, each with an id property, you can achieve this as follows:

const ids = this.item.specialties.map(item => item.id)
