You will have to follow the following procedure:

  1. Load data
  2. Change data
  3. Store data

This can be done as follows:

const rawData = localStorage.getItem("my-data") || "[]";
const data = JSON.parse(rawData);
data.push(new Date().toISOString());
localStorage.setItem("my-data", JSON.stringify(data));
console.log(data);

Here is a working example, as the code snippet component on StackOverflow does not support LocalStorage operations.
