Pass an object method an array of strings (Javascript)

Question

The goal is to pass an array of strings (Substitute teacher names) to the 'pickSubstituteTeacher' method and return one random teacher. I cannot figure out how to send an array of strings to the object method and return the random value.

class School {
  constructor(name, level, numberOfStudents) {
    this._name = name;
    this._level = level;
    this._numberOfStudents = numberOfStudents;
  }

  static pickSubstituteTeacher(substituteTeachers) {
    let ranNum = Math.floor(Math.random()*substituteTeachers.length);
    return substituteTeachers[ranNum];
  }
}

const school1 = new School('school1', 'two', 233);


let randomTeacher = School.pickSubstituteTeacher['teacher1','teacher2','teacher3'];

console.log(randomTeacher);

Answer 1

您必须在数组周围加上括号以表明该数组是该方法的参数。

let randomTeacher = School.pickSubstituteTeacher(['teacher1','teacher2','teacher3']);

Answer 2

You are sooo close...

Go with this: let randomTeacher = School.pickSubstituteTeacher(['teacher1', 'teacher2', 'teacher3']);
