JavaScript class Statement

Create a Car class, and then an object (myCar) based on the Car class

Notes

The syntax in a class must be written in "strict mode".

Unlike functions, class declarations are not hoisted (you must declare a class before you can use it).

Syntax

class className {
  // class body
}
