JavaScript String Destructuring

Perform String Destructuring In JavaScript

Destructuring is extracting values from data types such as arrays, objects and strings.

Arrays and objects destructuring can be assigned default values if the index is not defined. Nested destructuring is possible for data types with nested properties. The string data type is immutable and is a series of characters representing textual data.

Destructuring assignment syntax unpacks values from some primitive and non-primitive data structures into distinct variables.
