Multiline Strings

Creating a multiline string in the past involved effort and resulted in a lot of noise in code. Template literals may be single line or multiline—there is no special syntax to set the two apart, except for line breaks.

Here’s a multiline string with expressions in it.

literals/multiline.js
​ ​const​ name = ​'John Doe'​;
​ 
​ ​const​ message = ​`Dear ​${name}​,​
​ ​We're delighted to let you know that you have been included in​
​ ​our routine spam starting with this one.​
​ 
​ ​ You can thank us later.​
​ ​`​;
​ 
​ console.log(message);

Start the string with a backtick, continue each new line with a line break, and end the string with the ending backtick. Expressions in the string are optional.

The output of this code is

​ Dear John Doe,
​ We're delighted to let you know that you have been included in
​ our routine spam starting with this one.
​ 
​  You can thank us later.

Multiline strings preserve indentations, and that can be inconvenient if we have the template literals in an indented region, like within a function or an if condition. We’ll look at a possible workaround for that issue in the exercises at the end of this chapter.
