Destructuring is a convenient way of extracting multiple values from data stored in objects and Arrays. The destructuring assignment syntax is a JavaScript expression that makes it possible to unpack values from arrays, or properties from objects, into distinct variables.

Ex:- var a = [10, 20, 30];

[x, y, z] = a;
console.log(x) // 10
console.log(y) // 20
console.log(z) // 30

Left-hand side of the assignment to define what values to unpack from the sourced variable.

Array Destructuring

When destructuring Array, we use their index/positions in the assignment.

Array Passing to a Function

Array Returning from a Function

Nested Array Destructuring

Object Destructuring

When destructuring objects, we use the keys as variable names. This is how JavaScript knows which property of the object we want to assign.
