Hiring JavaScript Agencies: Complete Guide & Overview
JavaScript is a general-purpose programming language used extensively for web development. It runs directly in web browsers for interactive interfaces and can also run on servers, desktop applications, mobile applications, and developer tools. JavaScript supports event-driven and asynchronous programming and has a large ecosystem of libraries and frameworks. It is a core technology for frontend development and is also widely used in full-stack applications through runtimes such as Node.js.
For projects using JavaScript, teams should consider the application's requirements, expected scale, integration points, deployment environment, testing approach, and long-term maintenance. Choosing the technology should also take into account the existing skills of the development team and the libraries or services already used by the product.
