# unicorn/prefer-string-raw

> Require `String.raw` for strings that escape backslashes

In a normal string you write every backslash twice, which makes a Windows path or a regex source hard to read and easy to get wrong. In a `String.raw` template you write it once.

The rule skips a string that has another escape such as `\n`, ends with a backslash, or contains a backtick or `${`. `String.raw` can't express those.

`--fix` rewrites the string to a `String.raw` template.

## Examples

Reported:

{/* bad {"count": 2} */}
```js
const logs = "C:\\Users\\ada\\logs";
const version = new RegExp("\\d+\\.\\d+");
```

Not reported:

{/* good */}
```js
const logs = String.raw`C:\Users\ada\logs`;
const version = new RegExp(String.raw`\d+\.\d+`);

const lines = "C:\\logs\n"; // has another escape
const folder = "C:\\logs\\"; // ends with a backslash
```
