How to get all field names of javascript class?

@muriel.schmidt 

There are a few ways to get all field names of a JavaScript class:

1. Using Object.keys(): You can use the Object.keys() method to retrieve all the enumerable properties of an object, including the fields of a JavaScript class. Here's an example:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12

class MyClass {
  constructor() {
    this.field1 = "value1";
    this.field2 = "value2";
  }
}

const myObj = new MyClass();

const fieldNames = Object.keys(myObj);

console.log(fieldNames); // Output: ["field1", "field2"]

1. Using the getOwnPropertyNames(): The getOwnPropertyNames() method returns an array of all properties (including non-enumerable properties) found on a given object. Here's an example:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12

class MyClass {
  constructor() {
    this.field1 = "value1";
    this.field2 = "value2";
  }
}

const myObj = new MyClass();

const fieldNames = Object.getOwnPropertyNames(myObj);

console.log(fieldNames); // Output: ["field1", "field2"]

Note: Both Object.keys() and Object.getOwnPropertyNames() return an array of field names as strings.
