What is Go?
Go (or Golang) is a modern programming language developed by Google, designed for simplicity, performance, and scalability.
Key Features of Go ✅
-
Open Source & Cross-Platform: Runs seamlessly on Linux, Windows, and macOS.
-
Easy to Learn: Simple syntax, clean design — approachable like Python.
-
Fast Compilation: Ideal for large-scale systems where build speed matters.
-
High Performance: Execution speed is comparable to C/C++.
-
Great for Web Backends: Widely used in scalable server-side development.
-
Built-in Concurrency: Goroutines and channels make multitasking efficient and developer-friendly.
-
Rich & Growing Ecosystem: Standard library includes robust support for web servers, I/O, cryptography, and more.
What Go is not? ❌
-
Not Primarily for System Programming: While Go is powerful, it's not designed for low-level system programming (e.g. writing OS kernels or device drivers). Languages like C, C++, and Rust offer more control over memory, hardware access, and performance tuning.
-
Not Meant for Every Use Case: Go excels at web backends, network servers, and concurrent workloads, but may fall short in areas requiring fine-grained memory management, real-time constraints, or tight binary size control.
