What is destructuring assignment and its uses?

Question

I have been reading about Destructuring assignment introduced in ES6.

What is the purpose of this syntax, why was it introduced, and what are some examples of how it

Answer 1

The De-structured assignment of Javascript is probably an inspiration drawn from Perl language.

This facilitates reuse by avoid writing getter methods or wrapper functions.

One best example that I found very helpful in particular was on reusing functions that return more data than what is required.

If there is a function that returns a list or an array or a json, and we are interested in only the first item of the list or array or json, then we can simply use the de-structured assignment instead of writing a new wrapper function to extract the interesting data item.
