Array destructuring in LWC
Let's look at how to use Array Destructuring in LWC.
When we get data from Apex method processing it is one of the most important aspects of LWC.
It's a known fact that when we send a List from an Apex method we will receive it as an Array in LWC and when a Map is sent from Apex method an Object is received in LWC.
When we receive an Array in LWC not everything we might need all the elements of the Array and we might have to get a few elements out of it.
Let's look at how to get a few elements out of an Array using a concept in ES6 called Array destructuring.
In this class, we are sending all the values of a pick-list field Rating in Account object to Lightning Web Component.
In the LWC component if I were to fetch the first 2 items of the Array and assign it to a couple of local variables I will be using Array Destructuring (check the comments in the below code).
Hope that's helpful!
