HERZ-001 JAV : 0 Your score is: 0 ## <code> `${user}` </code> The code `${user}` is a template literal in JavaScript, which is a way to create strings dynamically by including variables or expressions inside it. Here's how it works: ### Template Literals Template literals are enclosed by backticks (`), not single or double quotes, and they allow for: 1. **Variable substitution**: ``` const user = "John"; const greeting = `Welcome ${user}!`; console(greeting); // Output: Welcome John! ``` Here, `${user}` is replaced by the value of `user`, which is "John". 2. **Expression evaluation**: ``` const count = 10; const sentence = `There are ${count * 2} letters in the alphabet.`; console(sentence); // Output: There are 20 letters in the alphabet. ``` Here, `${count * 2}` is evaluated to 20, and that's inserted into the string. ### Example Use in HTML In a web application, you might use template literals to dynamically generate HTML content: ``` const user = "John"; const message = `<code>Welcome ${user}</code>`; document.getElementById("message").innerHTML = message; ``` This would display "Welcome John" in the HTML element with an ID of "message". ### Conclusion The code `${user}` is a way to insert the value of `user` dynamically into an HTML string, enabling you to create personalized messages or content based on user data. - Free Trailer and English Subtitles srt.
