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         


        

Answer 1

ES6 has new features:

• Template literals
• Tagged template literals (tagged templates)

Which make working with strings easier. You wrap your text in `backticks`.

With this we can:

1. Interpolate variables

   let foo = "abc";
   
   console.log(`Welcome ${foo}`); // Welcome abc
   

2. Interpolate any kind of expression

   console.log(`2+3 = ${2+3}`) // 2+3 = 5
   

3. Declare strings with both ' and " quotation marks without having to escape anything.

   let foo = `foo is 'bar', "bar" is foo`
   
   console.log(foo); // "foo is 'bar', "bar" is foo"
   

4. Cleaner syntax for multi-line string

   let text = `foo is bar
   
   bar is foo`
   
   console.log(text);
   
   //"foo is bar
   
   //bar is foo"
   

5. Tagged templates, we can pass template literals to a function, here is how:

   let person = 'Mike';
   let age = 28;
   
   let output = myTag `that ${ person } is ${ age }`;
   
   function myTag(strings, personExp, ageExp) {
   
       // strings[0] gets value "that "
       // strings[1] gets value " is "
       // personExp  gets value " Mike "
       // ageStr     gets value "28"
   
       return strings[0] + personExp + strings[1] + ageExp;
   }
   
   console.log(output);
   
   // that Mike is 28
   

6. String.raw, we can get the raw form, here is the example:

   let text = String.raw `The "\n" newline won't result in a new line.'
   console.log(text);
   // The "\n" newline won't result in a new line.
