Embedding JavaScript


You want to include some found/pre-written JavaScript code inline with your CoffeeScript.


Wrap the JavaScript with backticks:

`function greet(name) {
return "Hello "+name;

# Back to CoffeeScript
greet "Coffee"
# => "Hello Coffee"


This is a simple way to integrate small snippets of JavaScript code into your CoffeeScript without converting it over to use CoffeeScript syntax. As shown in the CoffeeScript Language Reference you can mix the two languages to a certain extent:

hello = `function (name) {
return "Hello "+name
hello "Coffee"
# => "Hello Coffee"

Here the hello variable is still in CoffeeScript, but is assigned a function written in JavaScript.
