Difference (if there is any) between ` and ' in javascript [duplicate]

Question

Recently ran into some JS code that uses ` and '. I can't figure out if there is a different use for each apostrophe. Is there any?

Answer 1

' or " denotes a string

` denotes a template string. Template strings have some abilities that normal strings do not. Most importantly, you get interpolation:

var value = 123; console.log('test ${value}') //=> test ${value} console.log(`test ${value}`) //=> test 123 

And multiline strings:

console.log('test test') // Syntax error  console.log(`test test`) // test // test 

They have some other tricks too, more on template strings here: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/template_strings

Note they are not supported in all javascript engines at the moment. Which is why template strings are often used with a transpiler like Babel. which converts the code to something that will work in any JS interpreter.
