I am attempting to have a list of class objects within JavaScript. I have done in Flutter but seems to be a tad bit different in JavaScript. I have a class object

   class Sections{
	constructor(lecture, quiz, assignment, name){
		this.lecture = lecture;
		this.quiz = quiz;
		this.assignment = assignment;
		this.name = name;
	}
  }

This class will have multiple instances within one Chapter. so a list of this class needs to be created. Normally you would say List<Sections> VarName = []; but, in JavaScript the list variable type does not seem to be a thing. So does anyone know how to accomplish this?

So I made an array with objects. For example here, let's use people

    var people = [
        {
            id: 0,
    
            name: "John Doe",
    
            age: 47
        },
        {
            id: 1,
    
            name: "Jane Doe",
    
            age: 88
        },
        {
            id: 2,
    
            name: "Mason Louis",
    
            age: 17
        }
    ];

so now I can use people[1].name etc for accessing the data on each of these people. Someone just saw my code and said "That looks like total S**T".

What is the proper way to do this? I was thinking this way was fine, especially since it resembles JSON

EDIT: Would it be better to create a constructor and fill an array with instances?
