64. What is the difference between ES6 Class and ES5 implementation?

The main difference is that ES6 introduced a new syntax for creating classes, which is similar to the syntax used in other object-oriented programming languages like Java and Python. ES6 classes support constructor functions and inheritance, making object-oriented programming in JavaScript much more intuitive and easier to reason about. On the other hand, in ES5, creating classes involves using constructor functions and prototypes. Although this approach is more verbose, it still allows for object-oriented programming in JavaScript. Another difference is that ES6 classes are not hoisted whereas the constructor function used in ES5 implementation is hoisted to the top of the scope.
