Template Literals in JavaScript (Backtick Strings)

The usage of backticks (`) for strings in JavaScript is tied to the concept of template literals.

Template literals are a way to create strings that offer more functionality compared
to strings defined with single (') or double (") quotes.

Template Literals make for easy creation of dynamic strings.
They support multi-line strings without explicit newline characters.

Usage

  1. Basic Syntax:
  2. Defined with backticks (`).

  3. Can span multiple lines without requiring newline characters (like Go's string literals).

  4. Interpolation with ${}:

  5. Variables and expressions can be embedded within the string using ${expression} syntax.

  6. The expression inside ${} is evaluated, and the result is converted
    to a string and included in the template literal.

  7. Example: 

let user = 'Alice';  
let greeting = `Hello, ${user}!`;  
console.log(greeting);  // Output: Hello, Alice!
