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'
