To get objects value if its name contains dots with JavaScript, we can use square brackets.

For instance, we write

const mydata = {
  list: [
    {
      "points.bean.pointsBase": [
        { time: 2000, caption: "caption text", duration: 5000 },
        { time: 6000, caption: "caption text", duration: 3000 },
      ],
    },
  ],
};
const smth = mydata.list[0]["points.bean.pointsBase"][0].time;

to get the first entry in list with mydata.list[0]

And we get the "points.bean.pointsBase" property with ["points.bean.pointsBase"].
