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: doc.rs
    path of file: ./repos/ast-grep/crates/napi/src
    
    the code of the file until where you have to start completion: use crate::FrontEndLanguage;

use ast_grep_config::{DeserializeEnv, RuleCore, SerializableRuleCore};
use ast_grep_core::source::{Content, Doc, Edit, TSParseError};
use ast_grep_core::Language;
use napi::anyhow::Error;
use napi::bindgen_prelude::Result as NapiResult;
use napi_deri
    
  fn test_js_doc_multiple_node_replace() {
    let doc = JsDoc::new(
      "console.log(1 + 2 + 3)".into(),
      FrontEndLanguage::JavaScript,
    );
    let mut grep = AstGrep::doc(doc);
    let edit = grep
      .root()
      .replace("console.log($$$MULTI)", "log($$$MULTI)")
      .expect("should exist");
    grep.edit(edit).expect("should work");
    assert_eq!(grep.root().text(), "log(1 + 2 + 3)");
  }
