javascriptapostrophe

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

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?

Solution

  • ' 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
