Golang Interview Preparation Practice Tests

Go, often referred to as Golang, is an open-source programming language developed by Google and launched in 2009. It was designed by Robert Griesemer, Rob Pike, and Ken Thompson, who aimed to create a language that was efficient, readable, and simple to use. Go is statically typed, compiled, and syntactically similar to C, but with memory safety, garbage collection, structural typing, and CSP-style concurrency features.

One of the core features of Go is its approach to concurrency, which is implemented through ‘goroutines’ and channels. Goroutines are functions or methods that run concurrently with other functions or methods. They are lightweight and more memory-efficient than traditional threads, making Go particularly suitable for applications that require high concurrency, like web servers and network services. Channels, on the other hand, provide a way for goroutines to communicate with each other, allowing the safe sharing of data without explicit locks or condition variables.

Go’s standard library is another strong point, providing a robust set of utilities and packages out of the box. This includes tools for building HTTP servers, handling I/O operations, cryptography, and more, all of which are designed to seamlessly integrate with Go’s concurrency mechanisms. The language’s dependency management system, which evolved significantly with the introduction of modules in version 1.11, also contributes to Go’s appeal by simplifying code sharing and dependency tracking.

Go has been widely adopted in the tech industry, particularly in scenarios where performance and efficient resource utilization are critical. Companies like Google, Uber, and Dropbox use Go to power various components of their infrastructure. Its straightforward syntax, efficient compilation, and powerful standard library make it an excellent choice for developing fast, reliable, and scalable applications.

Frequently Asked Questions

How long do I have access to the course materials?

You can view and review the lecture materials indefinitely, like an on-demand channel.

Can I take my courses with me wherever I go?

Definitely! If you have an internet connection, courses on Udemy are available on any device at any time. If you don’t have an internet connection, some instructors also let their students download course lectures. That’s up to the instructor though, so make sure you get on their good side!
