- Display the Result: Present the result to the user, which can be easily achieved with an HTML input element set to read-only.
Here’s a brief breakdown of the JavaScript code provided above:
- Function Definition: The function
calculateDaysSincetakes a date string as input. It calculates the number of days since that date based on the current date and returns the result. - Element Selection: The code selects the input field where the result will be displayed.
