FAQs
Go (or GoLang) is a programming language designed by Google. It’s popular because it’s simple to learn, extremely fast (it compiles to machine code), and has built-in features for concurrency (goroutines), which makes it perfect for building modern backend systems that need to handle many tasks at once.
GoLang is best for high-performance applications. This includes:
* Cloud-Native applications and microservices.
* High-traffic APIs and web backends.
* Data processing pipelines and real-time systems.
* DevOps tools (like Docker and Kubernetes)
GoLang is a compiled language, making it significantly faster and more memory-efficient than Python (an interpreted language). Go excels at concurrency and building high-performance systems. Python excels at data science, AI/ML, and rapid development due to its vast libraries.
Goroutines are a key feature of Go. They are extremely lightweight “threads” managed by the Go runtime. This allows a single application to easily and efficiently handle tens of thousands of concurrent tasks, such as managing thousands of user connections at the same time.
GoLang Backend Development is the process of using Go to build the “server-side” of an application. This includes the business logic, database interactions, and the APIs that a mobile app or website communicates with.
Due to its high performance and demand in critical systems, hiring Go Developers can be a significant investment. A project from one of the Best GoLang Development Companies can range from $75,000 to over $400,000, depending on the complexity of the system.
Yes, GoLang is excellent for web development, but specifically for the backend. It’s used to build the fast, scalable APIs that power modern web applications. The front-end (what the user sees) is typically built with a JavaScript framework like React or Vue.js.
