The class expression

A class expression has a similar syntax to a class declaration. However, with class expressions, you are able to omit the class name. The body and behavior remain the same both ways.

Here is a code example to demonstrate how to define a class using a class expression:

const Student = class {     constructor(name) {         this.name = name;     } } const s1 = new Student("Eden"); console.log(s1.name); //Output "Eden"

Here, we stored a reference of the class in a variable and used it to construct the objects.

The previous code is the same as this code when written using a function:

const Student = function(name) {     this.name = name; }; const s1 = new Student("Eden"); console.log(s1.name); //Output "Eden"
