  Hi! Respect to the JSON part that you ask for help, here's the JSON part of my code:

  fetch('./data.json')
      .then(response => response.json())
      .then(data => {
          times = data;
          updateButtonStates(dayBtn);
          updateContent("daily");
      })
      .catch(error => console.error('Error:', error));
  

  This JavaScript code uses the Fetch API to fetch data from a local JSON file and then update the content of a web page. Here's a detailed explanation:

  1. fetch('./data.json'): Uses the fetch function to make an HTTP GET request to the data.json file located in the same folder as the current JavaScript file (indicated by ./).

  2. .then(response => response.json()): This then method is executed when the fetch request is successfully resolved. The function response => response.json() takes the response and converts it into a JSON object.

  3. .then(data => {...}): This second then method is executed when the JSON object is ready for use. Within the {...} block, three main tasks are performed:

     • times = data;: Assigns the retrieved data stored in the data object to a variable named times.
     • updateButtonStates(dayBtn);: A call to a custom function that updates the states of buttons on the web page, taking dayBtn as a parameter.
     • updateContent("daily");: A call to another custom function that updates the content of the web page with daily data, passing the value "daily" as a parameter.

  4. .catch(error => console.error('Error:', error)): This catch method is executed when an error occurs in the fetch request or in any of the then operations. In case of an error, the function error => console.error('Error:', error) prints an error message in the browser console.

  In summary, the code fetches data from a JSON file, processes it as a JSON object, and then updates the content and button states on the web page. If any errors occur, an error message is printed in the console.
