Strings as Sequences of Characters
A string is not just a single blob of text — it is an ordered sequence of individual characters, each occupying a specific position. The word "Hello" is a string made of five characters: H at position 0, e at position 1, l at position 2, l at position 3, and o at position 4. You can access any individual character by its index, measure the total number of characters with .length, extract a portion with .slice(), and much more. Strings are everywhere in real programs — names, messages, email addresses, passwords, search queries, button labels — virtually all the text a user sees or types is a string.

Template Literals
Template literals — strings written with backtick characters rather than quotes — are the modern, preferred way to work with text in JavaScript. They have two important advantages over regular string joining using the + operator. First, you can embed any expression — not just variable names but full calculations, function calls, or ternary operators — directly inside the text using ${ }. JavaScript evaluates whatever is inside the braces and converts the result to a string automatically. Second, template literals can span multiple lines naturally, without any special escape characters.
