String.raw() in JavaScript

JavaScript's String.raw() is a built-in method that provides a way to work with template literals in their raw form. We use String.raw() to interpret a template literally exactly as it is typed, without processing escape sequences like \n or \t.

String.raw() can be used directly with template literals to capture raw strings. Here’s how:

const rawString = String.raw`Hello\nWorld!`;
console.log(rawString); // Output: "Hello\\nWorld!"

In this example, the output retains the backslash (\) found in the escape sequence, treating it as a literal character.


While using String.raw(), the first argument requires a valid raw property. Failing to do so results in a TypeError:

try {
    const result = String.raw({}); // This will fail
} catch (e) {
    console.log(e.message); // TypeError: Cannot convert undefined or null to object

String.raw() is a great JavaScript utility for handling raw strings. It is especially useful when working with file paths, regular expressions, or wherever your escape sequences should not be processed as special characters.

It's got me out of a few headaches, so it's definitely a good one to remember in your JavaScript toolkit. ❤️
