Can you help with task 7?

Under .quickFacts(), create a static method named pickSubstituteTeacher. This method will receive one parameter, named substituteTeachers. The substituteTeachers parameter will take an array of strings.

Inside the method, randomly generate a whole number between 0 and one less than the length of the substituteTeachers array. Use this number to access and return the substitute teacher at that randomly generated index.

static pickSubstituteTeacher(substituteTeachers) {

substituteTeachers = [];

let randomTeacher = Math.floor(substituteTeachers.length * Math.random() - 1)

this.substitueTeachers[randomTeacher];

}

I can’t figure out who do it, thanks!
