How Do I Assign Multiline Strings to Variables in JavaScript?

Assigning Multiline String Literals to Variables in JavaScript

In Ruby, you can use a here-document to denote a multiline string literal. Converting this syntax to JavaScript can be tricky, as JavaScript doesn't inherently support here-documents.

Update: ES6 Template Literals

ECMAScript 6 (ES6) introduced template literals, which allow for multiline strings. These literals are enclosed in backticks (`), and support variable interpolation and other features:

var html = `
  <div>
    <span>Some HTML here</span>
  </div>
`;

ES6 template literals provide the most straightforward and elegant solution for multiline strings.

Original ES5 Solution

Before ES6, JavaScript had no built-in here-document syntax. However, you could approximate multiline strings by escaping newlines using the backslash character, like so:

"foo \
bar"

While this method is not as convenient as ES6 template literals, it was the standard approach before their introduction.
