Ask for suggestions

  • Create a file with the standard file extension of the language to indicate the preferred programming language to the AI.
  • Start to create a function with the name that describes its purpose (in this example we will use the JavaScript syntax)
    function getDaysInMonth(month, year) {
    (If your IDE automatically adds the closing curly brace, remove it, otherwise Copilot does not offer solutions)

    // Express server on port 3000 and return the current date
