Why Javascript?

What makes Javascript the right choice for modern engineering teams.

  • Versatile and interpreted

    JavaScript is a versatile, interpreted programming language that allows developers to write dynamic and interactive code for both client-side and server-side applications.

  • Cross-browser compatibility

    JavaScript is designed to run on all major browsers, ensuring consistent behavior and compatibility across different platforms.

  • Asynchronous programming

    JavaScript supports asynchronous programming, enabling the execution of non-blocking code for improved performance and responsiveness.

  • DOM manipulation

    JavaScript is used to manipulate the Document Object Model (DOM), allowing dynamic updates and interactions with HTML and XML documents.

  • Event-driven programming

    JavaScript follows an event-driven programming paradigm, responding to user actions and events on web pages.

  • Server-side development

    JavaScript can be used for server-side development with platforms like Node.js, allowing developers to build scalable and efficient server applications.

  • Extensive libraries and frameworks

    JavaScript has a rich ecosystem of libraries and frameworks, such as React, Angular, and Vue.js, for building robust and efficient web applications.

  • JSON (JavaScript object notation)

    JavaScript seamlessly integrates with JSON, a lightweight data interchange format, for efficient data exchange between the server and the client.

  • Responsive design

    JavaScript is crucial for implementing responsive design principles, enabling the creation of websites that adapt to different screen sizes and devices.

  • Regular expressions

    JavaScript supports regular expressions, facilitating powerful pattern matching and manipulation of strings.

Javascript in action

import React, { useState, useEffect } from 'react';
import axios from 'axios';

const App = () => {
  const [data, setData] = useState([]);
  const [loading, setLoading] = useState(true);

  useEffect(() => {
    const fetchData = async () => {
      try {
        const response = await axios.get('https://api.example.com/data');
        setData(response.data);
        setLoading(false);
      } catch (error) {
        console.error('Error fetching data:', error.message);
        setLoading(false);
      }
    };

    fetchData();
  }, []);

  return (
    <div>
      <h2>Complex Dummy Component</h2>
      {loading ? (
        <p>Loading data...</p>
      ) : (
        <ul>
          {data.map((item) => (
            <li key={item.id}>
              <strong>{item.name}</strong> - {item.description}
            </li>
          ))}
        </ul>
      )}
    </div>

Hiring Javascript developers — answered

Practical answers to the questions CTOs and founders ask us most often before they hire.

How quickly can I hire a Javascript developer from Krapton?

Within 24 hours of the initial call. We keep a bench of pre-vetted Javascript engineers, so once you confirm the brief we line up two or three shortlisted CVs within a business day and can onboard the selected developer within two.

How much does it cost to hire a dedicated Javascript developer from India?

Blended hourly rates for senior Javascript engineers typically fall in the $18–$35 USD range depending on seniority and engagement length — roughly 50–70% cheaper than equivalent talent in the US or UK, with no loss of code quality. Dedicated developers are billed monthly with no lock-in.

Are your Javascript developers full-time employees or freelancers?

Every Javascript developer you hire through Krapton is a full-time, in-house engineer — we never subcontract to freelancers or agencies. That means consistent code quality, signed NDAs, and a single point of accountability for your project.

Can I hire remote and offshore Javascript developers who work in my timezone?

Yes. Our New Delhi team works in IST and overlaps 4–6 hours per day with PST, EST, GMT, CET and AEST clients for live standups, pairing and code review. You get the cost advantage of offshore Javascript developers with enough real-time overlap to feel like an in-house team.

Who owns the code and IP my Javascript developers write?

You do — 100%. IP assignment and confidentiality are covered by the contract and a free NDA on request. All code lives in your repositories, on your infrastructure, under your accounts from day one.

What if a Javascript developer is not the right fit?

You get a free replacement guarantee for the first 30 days. If your developer is not delivering to expectations in that window, we replace them at no cost within five business days, and you only pay for hours worked by the original engineer.

Can you provide a whole Javascript team, not just one developer?

Yes. Many clients start with one Javascript developer and scale into a pod — for example a couple of Javascript engineers, a QA engineer and a part-time DevOps or UI/UX specialist — coordinated by a delivery lead. You scale the team up or down month by month.

Do you work with both startups and enterprises?

Both. Startups hire Javascript developers from Krapton to ship an MVP fast on a lean budget; enterprises use us for dedicated capacity, modernization and overflow delivery with NDAs, security controls and clear reporting. We tailor the engagement model and process to each.

Which engagement models do you offer for hiring Javascript developers?

Three: (1) a dedicated full-time developer billed monthly — best for ongoing products; (2) hourly time-and-materials — best for research or variable-load work; (3) fixed-price milestones — best for well-scoped builds. We recommend the right fit after a 30-minute discovery call.
