You are not alone if you are looking to hire a JavaScript programmer. Fortunately, JavaScript programmers are plentiful. According to Statista, the JavaScript programming language community has over 17.4 million software developers. Also, JavaScript is the most used programming language, with over 65% of software developers worldwide using it.

JavaScript Programming

  1. Website Development: JavaScript is a server-side and client-side programming language used by 98.3% of all existing websites (over 50 million websites). The JS scripting language is so popular because it simplifies building interactive and dynamic websites.

  2. Front-End Web Development: Front-end developers use JS to build highly functional user interfaces. They achieve this by using JavaScript to manipulate a webpage’s HTML and CSS.

  3. Back-End Development: JavaScript back-end developers can use Node.js for server-side development. They can also build server-side applications, APIs, and services with frameworks like Express.js or NestJS.

  4. Mobile App Development: Developers can build cross-platform mobile apps with JavaScript frameworks like React Native and NativeScript. Such apps can work on both iOS and Android platforms.

  5. Single-Page Applications (SPAs): JavaScript developers use JS frameworks like Angular.js, React.js, or Vue.js to build SPAs. SPAs provide a smoother and more seamless user experience by allowing users to view all content on one page.

  6. Plugin and Library Development: JavaScript developers can build reusable plugins and libraries to boost an existing framework's functionality. They also build WordPress plugins and themes that can boost a WordPress site’s interactivity and functionality.

As you can see, you have a lot to gain if you hire a JavaScript programmer. However, with millions of JavaScript programmers to choose from, how and where can you find the right expert for your project? All your answers are here, starting with if you should hire a freelance JavaScript developer or an in-house developer.

Should you hire in-house or freelance devs?

When looking to hire a JavaScript developer, you can choose between hiring a freelance JavaScript developer or an in-house team. A freelance Javascript developer is a programmer who works independently (self-employed).

Since they are not employees, the same laws or service terms that apply to your staff won’t apply to freelancers. For instance, you don’t need to provide a freelancer with health insurance or paid time off. Such developers typically work remotely and charge per hour or per project.

Depending on your budget or preferences, you can pick between vetted and unvetted freelancers. Unlike unvetted freelance JavaScript programmers, vetted freelancers have verified skills, credibility, and qualifications.

Hiring a vetted JavaScript expert is typically a safer bet because they have proven work experience and skills. However, unvetted freelancers typically charge less to compete with vetted freelancers. Lastly, freelancers are the most inexpensive option for businesses looking to hire developers. Their affordability makes hiring freelancers a popular option among startups or other businesses on a tight budget.

On the other hand, in-house JavaScript developers are experts hired as full-time employees of your business. Hiring an in-house development team ensures that you have professionals you can easily reach to handle your mobile or web application development project.

However, hiring an in-house JavaScript developer costs more than freelancers because you have to pay salaries to your full-time employees. Even if you don’t have any JavaScript development project for months, you still have to pay in-house JavaScript developers salaries. Other downsides of in-house hiring include a lack of talent diversity and limited team scalability.

Are there other options to hire a JavaScript programmer?

An excellent alternative is to hire a full-service web development agency. Fully managed web development agencies offer a perfect blend of the advantages of a freelance JavaScript engineer and an in-house team. For example, a fully managed team costs less than hiring an in-house JavaScript programmer.

Also, a fully managed team doesn’t come with the uncertainties typically associated with hiring a freelancer. Examples of such uncertainties include a freelancer’s capability or reliability.

The top fully managed development agencies (like DevSquad) have an experienced and well-equipped team of software development professionals. These experts include individuals who can use JavaScript and other programming languages to help you achieve your product goals.

You can hire a fully managed team on a per-project basis, and they can tailor their services to fit your budget. Also, instead of hiring them for just JavaScript development services, you can let them handle all aspects of building and optimizing your mobile or web apps.

4. Codementor

hire freelance javascript developer

Codementor is the ideal platform for finding and hiring highly qualified and vetted JavaScript programmers. However, unlike Upwork, you can only hire software developers on Codementor.

Cost analysis of different methods of hiring

JavaScript’s open-source nature means it’s free to use, making it one of the most affordable options for building websites and apps. Other factors that make the programming language cost-effective are the abundance of free JavaScript libraries, frameworks, and community support.

However, developers don’t work for free, and how much you’ll pay for JavaScript web or app development will depend on the JS programmer(s) you hire. Below is a comprehensive cost analysis of the three options available to businesses looking to hire a JavaScript programmer.

1. In-House Hiring

If you hire a JavaScript programmer as a full-time, in-house employee, you get unrestricted access to a dedicated expert. However, it is the costliest hiring option for the following reasons:

  • Salary and Benefits: You have to pay salaries to full-time employees. Also, you have to provide benefits such as health insurance, paid time off, and retirement plans. Even if an in-house developer doesn’t work on any projects for several months, you still have to pay them.

  • Infrastructure and Resources: You must provide employees with office equipment, working space, and other resources they need to do their jobs. The cost of equipping employees is an expense you can avoid if you outsource JS projects.

  • Recruitment Costs: According to an SHRM study, hiring a full-time employee costs about $4,700 on average. The figure excludes the cost of employee training and salaries.

In summary, the amount you’ll spend on an in-house JS developer within a year far exceeds the cost of outsourcing to a freelancer or fully managed team.

2. Freelance Hiring

Hiring a freelancer is generally the least expensive option if you want to hire a JavaScript programmer. Several factors contribute to JS freelancers being less expensive. For instance, unlike full-time employees who take a while to onboard, settle in, and become productive, freelancers start earning their keep as soon as they accept a project. This means freelancers deliver returns on investment faster than in-house employees.

Other factors that make freelance hiring less expensive are:

  • Hourly or Project-Based Rates: You only pay freelancers for work done, and the payment arrangement may be hourly or project-based. However, note that vetted and more experienced freelancers typically charge higher rates.

  • No Employment Benefits: Unlike full-time employees, you don’t have to provide freelancers costly benefits, such as healthcare or retirement plans.

However, hiring freelancers comes with a hidden cost, and that’s the cost of searching for suitable freelancers. Since millions of freelance JS developers exist, finding the right one for your project can take weeks, and time is money. Also, should you hire the wrong freelancer, it can compromise or frustrate your product development plans, which is another cost.

3. Outsourcing

Outsourcing involves hiring a JS development company or agency to handle your JavaScript project. Upfront, outsourcing costs more than hiring a freelancer but less than in-house hiring. However, in the long run, outsourcing your JS development work to a fully managed team like DevSquad has several advantages, such as:

  • Project-Based Pricing: You only need to pay for the project, and the price will depend on the duration and complexity of your project. The price you pay will also cover development costs and additional services like QA, project management, and more. A freelancer or in-house developer won’t offer such services, meaning outsourcing offers more bang for your buck.

  • Guarantee: Reputable development agencies back up their work with guarantees. The guarantee ensures that the team will keep working on your project until you are happy. Most freelancers don’t offer such guarantees.

However, note that outsourcing to a fully managed agency is not your most cost-effective option if you only need JS services. Hiring a fully managed agency only offers optimal cost benefits if you want experts to handle your entire product development project.

Skip the hassle of finding, sorting, and interviewing hundreds of people to hire JavaScript programmers for your project. At DevSquad, we have JavaScript developers and every other specialist you need to take your product development from ideation to launch.
