`String.raw` when last character is `\`

Question

String.raw is very useful. For example:

let path = String.raw`C:\path\to\file.html`

However, when the last character of the template string is \, it becomes an syntax error.

let path = String.raw`C:\path\to\directory\`

Uncaught SyntaxError: Unterminated template literal

Tentatively, I use this method.

let path = String.raw`C:\path\to\directory\ `.trimRight()

Can I write template string which last character is \ using String.raw?

Here are a few different possible workarounds. My favorite is probably creating a custom template tag dir to solve the problem for you. I think it makes the syntax cleaner and more semantic.

let path

// Uglier workarounds
path = String.raw `C:\path\to\directory${`\\`}`
path = String.raw `C:\path\to\directory`+`\\`
path = `C:\\path\\to\\directory\\`

// Cleanest solution
const dir = ({raw}) => raw + `\\`

path = dir `C:\path\to\directory`

console.log(path)
