String.raw()

// Create a variable that uses a Windows
// path without escaping the backslashes:
const filePath = String.raw`C:\Development\profile\aboutme.html`;

console.log(`The file was uploaded from: ${filePath}`);
// Expected output: "The file was uploaded from: C:\Development\profile\aboutme.html"

String.raw(callSite, ...substitutions);

String.raw`templateString`;

String.raw`Hi\n${2 + 3}!`;
// 'Hi\\n5!', the character after 'Hi'
// is not a newline character,
// '\' and 'n' are two characters.

String.raw`Hi\u000A!`;
// 'Hi\\u000A!', same here, this time we will get the
//  \, u, 0, 0, 0, A, 6 characters.
// All kinds of escape characters will be ineffective
// and backslashes will be present in the output string.
// You can confirm this by checking the .length property
// of the string.

let name = "Bob";
String.raw`Hi\n${name}!`;
// 'Hi\\nBob!', substitutions are processed.

// Normally you would not call String.raw() as a function,
// but to simulate `foo${2 + 3}bar${'Java' + 'Script'}baz` you can do:
String.raw(
  {
    raw: ["foo", "bar", "baz"],
  },
  2 + 3,
  "Java" + "Script",
); // 'foo5barJavaScriptbaz'
// Notice the first argument is an object with a 'raw' property,
// whose value is an iterable representing the separated strings
// in the template literal.
// The rest of the arguments are the substitutions.

// The first argument’s 'raw' value can be any iterable, even a string!
// For example, 'test' is treated as ['t', 'e', 's', 't'].
// The following is equivalent to
// `t${0}e${1}s${2}t`:
String.raw({ raw: "test" }, 0, 1, 2); // 't0e1s2t'
