【解決方法】データ構造 – "これ" キーワード

こんにちは、みんな、

いくつかの課題を解決していますが、このタスクを解決する方法がわかりません。

let classroom = {
    numOfStudents: 0,
    schoolHours: false,
    playtime: false,
    openSchool: function() {
        this.schoolHours = true;
        this.numOfStudents = 20;

*Inside the breakTime function, and using the this keyword where necessary, check if the key schoolHours is true, and if it is, set the key playtime to true

What I have tried:

let classroom = {
    numOfStudents: 0,
    schoolHours: false,
    playtime: false,
    openSchool: function() {
        this.schoolHours = true;
        this.numOfStudents = 20;
    },
    breakTime: function() {
       
           
     this.playTime= true;   
       
    }
};


classroom.openSchool(); 
console.log(classroom.numOfStudents);
classroom.breakTime();
console.log(classroom.playTime);
