Template literals with nested backticks(`) in ES6

Question

How can I write a template literal in ECMAScript 6 that will contain backticks(`) in and by itself, (i.e. nested backticks)?

For example:

var qu

To escape all special characters, not just the backticks:

let str = '`Hello`\\n${world}';
let escacped = str.replace(/\\|`|\$/g, '\\$&');
console.log(eval('`' + escaped + '`') === str); // test

I needed this for some code generation stuff. The str was the content of a JavaScript file and the goal was to put this content into a string literal variable into another generated JavaScript file.

Sadly it seems there is (2019) no native JavaScript function for this escaping. The characters that needs to be replaced are: `, \, $ and \.
