What I learned

• The innerHTML property sets or returns the HTML content (inner HTML) of an element.
• The parseFloat() method parses a value as a string and returns the first number.
• The textContent property sets or returns the text content of the specified node, and all its descendants.
• The addEventListener() method attaches an event handler to the specified element.
• The toFixed() method converts a number to a string.
• The toFixed() method rounds the string to a specified number of decimals.
• The equality operator (==) checks whether its two operands are equal, returning a Boolean result. Unlike the strict equality operator, it attempts to convert and compare operands that are of different types.

  background-image: url("images/icon-dollar.svg");
  background-color: white;
  background-position: 10px 10px;
  background-repeat: no-repeat;

  Css code to display icon inside the input 

function cantBeZero() {
  const numOfPeople = document.querySelector(".number-of-people").value;
  if (numOfPeople == "0") {
    document.getElementById("error").textContent = "can`t be zero";
    iniTialize(tipAmount);
    document.getElementById("total-amount").textContent = "$0.00";
  }
}

if statement to be executed if the user enter 0 as number of people to be split the bill, it will display an error message that can't be zero.
