How to make the this in the static function of the ES6 class point to the function itself

Question

I want get the static function name in ES6 class, and I did not get the correct result when I did this.

class Point {
  static findPoint() {
    console.log(this.name) // <- I want to print "findPoint" but get "Point"
  }
}
Point.findPoint()

What can I do to get the name of the static method?

Answer 1

One option is to create an Error and examine its stack - the top item in the stack will be the name of the current function:

 class Point { static findPoint() { const e = new Error(); const name = e.stack.match(/Function\\.(\\S+)/)[1]; console.log(name); } } Point.findPoint(); 

While error.stack is technically non-standard, it's compatible with every major browser, including IE.

Answer 2

this.name refers class name. Use this.findPoint.name to get static function name. Syntax must be object.someMethod.name . You have to say which method name you want. Hope this will help you.

class Point {
  static findPoint() {
    console.log(this.findPoint.name)
  }
}
Point.findPoint()
