+Destructuring means to break down a complex structure into simpler parts. With the syntax of destructuring, you can extract smaller fragments from objects and arrays. It can be used for assignments and declaration of a variable.
+
+Destructuring saves you time and lines of code. One line accomplishes what 2 or 10 lines of code do. Specifically for React destructuring helps you keep your code DRY.
