Description

When the click event happens, you can use JavaScript to update an HTML element. For example, when a user clicks the "Get Message" button, it changes the text of the element with the class message to say "Here is the message". This works by adding the following code within the click event: document.getElementsByClassName('message')[0].textContent="Here is the message";

Instructions

Add code inside the onclick event handler to change the text inside the message element to say "Here is the message".

Tests

tests:
  - text: Your code should use the <code>document.getElementsByClassName</code> method to select the element with class <code>message</code> and set its <code>textContent</code> to the given string.
    testString: assert(code.match(/document\s*\.getElementsByClassName\(\s*?('|")message\1\s*?\)\[0\]\s*\.textContent\s*?=\s*?('|")Here is the message\2/g));
