Calling a typescript function named in a variable

Question

I am working on Ionic2 app. I am calling a function from a a Page. Is it possible that I use a variable name in function call. e.g.

original code: this._userDataService.getGrandQuestionsFromServer(this.passedId, newLevel)

expected code::

this._userDataService.get`${this.questionModuleName}`QuestionsFromServer(this.passedId, newLevel) 

Answer 1

You should be able to achieve this with bracket notation. Here is a working example:

const obj = {
  foobar(arg) {
    console.log(arg);
  }
};

const bar = "bar";
obj[`foo${bar}`]("It works!");

In your code, please try this:

this._userDataService[`get${this.questionModuleName}QuestionsFromServer`](this.passedId, newLevel)
