JavaScript Development Company Hiring Guide

What is a JavaScript development company?

A JavaScript development company is a company that develops and maintains web applications and software using JavaScript, a widely used programming language for front-end and back-end development. Its expert developers specialize in various JavaScript frameworks and libraries, such as React, Angular, Vue.js, Node.js, and jQuery, delivering intuitive and user-friendly websites.

Businesses often seek the help of a JavaScript development agency to address challenges, such as:

  • Lack of skilled in-house talent
  • Outdated legacy systems in place
  • Limited technical expertise to handle complex projects
  • Tight development timeline
  • Budget constraints in hiring an in-house development team
  • Limited foresight of industry trends and best practices

Hiring JS development services ensures that a business’ website, software, or application has a modernized user interface and provides a seamless user experience. By partnering with a reputable JavaScript development company, businesses can unlock the full potential of their online presence, enhance user satisfaction, and drive growth.

Success story

Our team of experts handpicked this case study to emphasize the benefits of hiring a reputable JavaScript development company to drive business growth:

  • Challenge: FINN, a German-based car company, struggled with organizing its operations and automating its processes as it expands to the US. However, its current subscription system relies on older technologies like manual spreadsheets and emails. The car company needed a partner to transform its internal tools to optimize workflows and make the app easy to navigate for users.
  • Solution: Cheesecake Labs helped FINN’s existing engineering team automate its processes. It also modernized its back end and internal tools by adding key features in its customer portal, allowing users and team members to easily and efficiently perform tasks like ordering or making account changes. Using Node.js, Typescript, and a PostgreSQL database, Cheesecake Labs transformed FINN’s US operations.
  • Results: The partnership resulted in an over 1,200+ increase in subscription for FINN. The internal tools built by Cheesecake Labs also generated significant usage, with a boost of 6,000+ page views per month.

Here’s a table showing how JavaScript developers charge differently based on where they are based:

Why should I hire a JavaScript development agency?

You should hire a JavaScript development agency for its technical expertise in the JavaScript programming language, from its core syntax to advanced frameworks and libraries. Beyond technical proficiency, a JavaScript development agency often strongly understands the broader web development ecosystem. This knowledge allows them to integrate JavaScript seamlessly with other technologies, creating cohesive and user-friendly applications.

Moreover, you should hire a JavaScript development agency because it:

  • Has seasoned programmers with proven expertise in JavaScript
  • Deploys efficient development processes to reduce development time
  • Mitigates common risks in the development process
  • Helps your website reach a wider audience by optimizing your website
  • Increases productivity for faster time to market

  • Challenge: AskIris, a healthcare mobile application, wanted to address the challenge of hospitals’ inefficient supply rooms, where nurses and other medical professionals spend significant time searching for necessary supplies.
  • Solution: Designli developed the minimum viable product (MVP) by prioritizing easy-to-implement features using CSV workflows. To accommodate various hospital systems, the JavaScript development agency designed a customizable solution where hospitals can tailor the app to their specific needs, ensuring a seamless fit with their existing infrastructure. Designli used JavaScript frameworks like AngularJS and NodeJS, along with the cross-platform capabilities of Flutter to enable a scalable backend and a versatile app.
  • Results: The collaboration resulted in a successful working relationship between the AskIris and Designli teams, delivering the features needed for the app within budget and on time. With the successful deployment of the app, the client saw tangible improvements in a hospital’s supply room efficiency and streamlined inventory management.
