I have a class to pass data but when I call the class method this data appears as null. Why?

class Test {

    constructor(data) {
        this.myData = data;
    }

    MyFunction = () => {
        return this.myData;
    };
}

When I install this Class the console returns to me null

<script type="text/javascript">

    var t = new Test({"data1", "data2", "data3"});
    //
    console.log( t.MyFunction() );

</script>

    You probably want to MyFunction (){ instead of MyFunction = () => {

Class methods shall be declared with : () => { or abbreviating directly to (){... or as we would do in an object.

in addition, the syntax of that data that you pass to class when instances are wrong. You are using {'string', 'string'}... I think you want to [] to get an array.

Example:

class Test {

  constructor(data) {
    this.myData = data;
  }

  MyFunction() {
    return this.myData;
  };
}

var t = new Test([
  "data1",
  "data2",
  "data3"
]);

console.log(t.MyFunction());

  • The problem was one of my functions was static and should not, but thanks for the help
