FAQs
JavaScript is a programming language essential for web development that allows creating dynamic web pages and applications. It’s one of the most popular languages for a number of reasons:
- High performance
due to JavaScript’s capabilities like just-in-time compilation and asynchronous execution
- Versatility
thanks to both client- and server-side support
- Platform independency
allowing for the creation of web, mobile, and desktop applications that run on different operating systems and browsers
- A massive ecosystem
of frameworks, libraries, and tools that help developers build and launch software faster
- One of the biggest communities
that offers strong support for developers, including documentation, tutorials, forums, open-source projects, etc
The time needed to develop a JavaScript solution depends primarily on the type of application you want to build. JS product development generally takes from 6 weeks for a basic JavaScript application to 6 months in case of a large-scale, complex solution.
The cost of JavaScript app development can differ greatly. When calculating the total price, companies should
factor in the number and complexity of software features, the integration of advanced technologies, the JS
development team’s size and composition, and other aspects.
The cost for an application with basic features and a simple user interface can start at
$10,000. However, the pricing can rise up to $400,000 for advanced
solutions.
To get a more precise cost estimation for your custom JavaScript development project, reach out to our
consultants.
JavaScript is widely used to create various types of web applications (including single-page applications (SPAs), server-side rendered (SSR) applications, and progressive web applications (PWAs)) and cross-platform mobile applications. There are also numerous JavaScript frameworks that are used for the development of desktop apps, server-side solutions, and web and mobile games.
Some of the most popular JS frameworks, libraries, and tools include:
- React.js, Next.js, Angular (AngularJS), and Vue.js used in frontend development
- Node.js, Express, and NestJS that facilitate backend development
- React Native for mobile development
