JavaScript never had a true good way to handle multiline strings, until 2015 when ES6 was introduced, along with template literals.

Template literals are strings delimited by backticks, instead of the normal single/double quote delimiter.

They have a unique feature: they allow multiline strings:

const multilineString = `A string
on multiple lines`

const anotherMultilineString = `Hey
this is cool
a multiline
st
r
i
n
g
!
`
