Creating multiline strings in JavaScript



I have the following code in Ruby. I want to convert this code into JavaScript. what's the equivalent code in JS?



text = <<"HERE"
This
Is
A
Multiline
String

HERE

Answer



Update:



ECMAScript 6 (ES6) introduces a new type of literal, namely template literals. They have many features, variable interpolation among others, but most importantly for this question, they can be multiline.



A template literal is delimited by backticks:



var html = `


Some HTML here

`;


(Note: I'm not advocating to use HTML in strings)



Browser support is OK, but you can use transpilers to be more compatible.







Original ES5 answer:



Javascript doesn't have a here-document syntax. You can escape the literal newline, however, which comes close:



"foo \
bar"
