How can you concatenate a string and a variable in JavaScript?
In the given example, JavaScript is used to concatenate a string and variables to create a dynamic message. The variables include name with the value "John", age with the value 25, and profession with the value "web developer". The message is constructed using template literals enclosed in backticks ( ), allowing variables to be inserted directly using ${} syntax. The resulting message is assigned to the message variable.
Finally, JavaScript accesses the HTML element with the ID "output" using document.getElementById() and sets its innerHTML to the value of the message variable, effectively displaying the dynamic message on the web page.
