Simple Javascript tip calculator code
Tip is typically calculated as a percentage of the total bill amount that is paid to a service worker such as a server, bartender, or hairdresser, as a way to show appreciation for their service. The exact percentage of the tip can vary depending on the country, region, and service industry, but it is usually between 15% and 20% of the total bill. To calculate the tip amount, you multiply the total bill amount by the tip percentage as a decimal.
