You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: for_in_statement.rs
    path of file: ./repos/biome/crates/biome_js_formatter/src/js/statements
    
    the code of the file until where you have to start completion: use crate::prelude::*;

use crate::utils::FormatStatementBody;
use biome_formatter::{format_args, write};
use biome_js_syntax::JsForInStatement;
use biome_js_syntax::JsForInStatementFields;

#[derive(Debug, Clone, Default)]
pub(crate) struct FormatJsForInStatement;

impl Format
    
    fn fmt_fields(&self, node: &JsForInStatement, f: &mut JsFormatter) -> FormatResult<()> {
        let JsForInStatementFields {
            for_token,
            l_paren_token,
            initializer,
            in_token,
            expression,
            r_paren_token,
            body,
        } = node.as_fields();

        let for_token = for_token.format();
        let initializer = initializer.format();
        let in_token = in_token.format();
        let expression = expression.format();

        write!(
            f,
            [group(&format_args!(
                for_token,
