Understanding Class Fields and Static Properties

Hello! Welcome to this article about Class Fields and Static Properties!
ES15 added the ability to define class fields and static properties directly within the class body. This eliminates the need for constructor functions to initialize properties, leading to cleaner and more concise code. This is about understanding this new feature!

1. Define a class.

You need to define a class to use it:

class myClass {
}
Copy after login

2. Put the properties in the class.

Putting the properties in the class defines the properties:

class myClass {
    property1;
    property2;
}
Copy after login

You can add as many properties as you need.

3. Add the constructor() function.

Add the constructor function to define the keys in the this object for the properties:

class myClass {
    property1;
    property2;
    constructor(property1, property2) {
        this.property1 = property1;
        this.property2 = property2;
    }
}
Copy after login

4. Example

This is an example of using this new feature in JS:

class Person {
    name;
    age;
    constructor(name, age) {
        this.name = name;
        this.age = age;
    }
}
Copy after login
