+//! This module contains the [`js_string`][crate::js_string] macro and the

+//!
+//! The [`js_string`][crate::js_string] macro is used when you need to create a new [`JsString`],

+/// Utility macro to create a [`JsString`].
+///
+/// # Examples
+///
+/// You can call the macro without arguments to create an empty `JsString`:
+///
+/// ```
+/// use boa_engine::js_string;
+///
+/// let empty_str = js_string!();
+/// assert!(empty_str.is_empty());
+/// ```
+///
+///
+/// You can create a `JsString` from a string literal, which completely skips the runtime
+/// conversion from [`&str`] to [&\[u16\]][slice]:
+///
+/// ```
+/// # use boa_engine::js_string;
+/// let hw = js_string!("Hello, world!");
+/// assert_eq!(&hw, "Hello, world!");
+/// ```
+///
+/// Any `&[u16]` slice is a valid `JsString`, including unpaired surrogates:
+///
+/// ```
+/// # use boa_engine::js_string;
+/// let array = js_string!(&[0xD8AFu16, 0x00A0, 0xD8FF, 0x00F0]);
+/// ```
+///
+/// You can also pass it any number of `&[u16]` as arguments to create a new `JsString` with
+/// the concatenation of every slice:
+///
+/// ```
+/// # use boa_engine::{js_string, js_str, JsStr};
+/// const NAME: JsStr<'_> = js_str!("human! ");
+/// let greeting = js_string!("Hello, ");

-/// Utility macro to create a [`JsString`].
-///
-/// # Examples
-///
-/// You can call the macro without arguments to create an empty `JsString`:
-///
-/// ```
-/// use boa_engine::js_string;
-///
-/// let empty_str = js_string!();
-/// assert!(empty_str.is_empty());
-/// ```
-///
-///
-/// You can create a `JsString` from a string literal, which completely skips the runtime
-/// conversion from [`&str`] to [&\[u16\]][slice]:
-///
-/// ```
-/// # use boa_engine::js_string;
-/// let hw = js_string!("Hello, world!");
-/// assert_eq!(&hw, "Hello, world!");
-/// ```
-///
-/// Any `&[u16]` slice is a valid `JsString`, including unpaired surrogates:
-///
-/// ```
-/// # use boa_engine::js_string;
-/// let array = js_string!(&[0xD8AFu16, 0x00A0, 0xD8FF, 0x00F0]);
-/// ```
-///
-/// You can also pass it any number of `&[u16]` as arguments to create a new `JsString` with
-/// the concatenation of every slice:
-///
-/// ```
-/// # use boa_engine::{js_string, js_str, JsStr};
-/// const NAME: JsStr<'_> = js_str!("human! ");
