Node.js simply get command parameters

class Argvs {
  constructor() {
    this.argvsAll = this.argvsAll();
  }
  argvsAll() {
    return process.argv.slice(2).reduce((acc, item) => {
      item = item.split(/=/);
      const [k, v] = [item[0].replace(/-/gi, ''), item[1]];
      acc.push({
        [k]: v
      });
      return acc;
    }, [])
  }

  argvsGet(k) {
    return this.argvsAll.reduce((acc, item) =>
      acc ?
      acc :
      (k in item) ?
      acc = item[k] :
      acc, false)
  }
}

// λ node server.js --name=ajanuw --post=14
let a = new Argvs();
console.log( a.argvsAll); // [ { name: 'ajanuw' }, { post: '14' } ]
console.log( a.argvsGet('name')); // ajanuw
console.log( a.argvsGet('post')); // 14
