How to get Last git Commit in Js file

Pre-Requisite:

How to use git.
Purpose of git.

Motivation:

You can collect following values inside the js file.
What is the subject of latest git commit.
what is the branch of latest git commit.
what is the hash of latest git commit and so on.

{
  "shortHash": "d2346fa",
  "hash": "d2346faac31de5e954ef5f6baf31babcd3e899f2",
  "subject": "initial commit",
  "sanitizedSubject": "initial-commit",
  "body": "this is the body of the commit message",
  "authoredOn": "1437988060",
  "committedOn": "1437988060",
  "author": {
    "name": "Ozan Seymen",
    "email": "oseymen@gmail.com"
  },
  "committer": {
    "name": "Ozan Seymen",
    "email": "oseymen@gmail.com"
  },
  "notes": "commit notes",
  "branch": "master",
  "tags": ['R1', 'R2']
}

Step:

Node provide us Library for this purpose npm i git-last-commit.
Create a file Git.js and add this function here.

const git = require("git-last-commit");
function getGitCommit() {
  return new Promise((res, rej) => {
    git.getLastCommit((err, commit) => {
      if (err) {
        return rej(err);
      } else {
        return res(commit);
      }
    });
  });
}
module.exports = {
  lastGitCommit: getGitCommit,
};

This function will return the Value of latest git commit, Call this function in other files like this.

const axios = require('axios');
const {lastGitCommit} = require('./Git');
const gitCommit = [];
const gitInfo = async () => {
  const response = await lastGitCommit();
  // console response and check if anything else you need.
  gitCommit.push(response);
  return response;
};
gitInfo();

Now just extract the values from gitCommit.
const hash= gitCommit[0].subject.
