class A{
    // Disallow external instantiation
    private constructor() {
    }
}

After compilation

var A = /** @class */ (function () {
  function A() {
  }
  return A;
}());

var A = /** @class */ (function () {
  function A() {
    // To prohibit external instantiation, the following method is more friendly
    // This is added manually, can it be automatically generated?😊😊😊
    // This is more in line with the characteristics of `private constructor`
    if (new.target === A) { // es6
      throw Error('Prohibit instantiation')
    }
    
    if (this.constructor === A) { // old version
      throw new Error("Prohibit instantiation");
    }
  }
  return A;
}());

You didn't fill out the issue template properly.

This is out of scope. private is intentionally a compile time only construct.

Thank you for your answer.
My scenario is: I wrote a singleton pattern with ts, compiled it and ran it on the client. I saw that the compiled code still supports instantiation. At this time, I need to manually add code to prohibit instantiation. So I asked this question, but it is not that important.
