Can Go Be Used in Web Development?

Oct 06, 2023 by Natalie Schooner

Recently I saw an interesting post on Reddit: “I would like to be more full-stack,” user Fenugurod said. “I was studying Tailwindcsss and I’m pretty sure I can create really nice UIs with it. But what do you guys think about web development with Go? Most of my friends simply say to embrace the JS ecosystem with Nuxt or Next and use Go simply as an API.”

How to Become a Golang Engineer (on the Back-End)

Feb 23, 2023 by Natalie Schooner

“Guys, I’ve got an idea. What if we could design a language that’s easy to read like Python, but fast? That has a slim feature-set like C, but is good for web development? That’s compiled like Java, but doesn’t need a VM?”

How to Use Golang's Generics [Updated since 1.18]

Dec 06, 2021 by Lane Wagner

Generics in Go have been released with Go 1.18! This is one of the most eagerly-awaited features since the release of the language. Many devs have gone so far as to say Go’s previous lack of generic types made the language too painful to use at all. Let’s dive into what generics are, why you might use them in your own projects, and how they work in Go.

Golang (or Go) and Java offer an interesting comparison because despite their wide differences, there are also key similarities in how and where they’re used by programmers.

What is Go Good For? (And What Is Golang Used For?)

Jul 16, 2021 by Jamie Dunmore

In 2007, frustrated by some of C++’s inefficiencies and overcomplicated nature, and desiring a programming language designed specifically for multi-core processors and effectively managing large projects, three Google engineers, Robert Griesemer, Rob Pike, and Ken Thompson, designed the Go language.

Golang vs C++: Which is Best For Your Next Project

Jul 12, 2021 by Meghan Reichenbach

Needing to be a math genius to learn to code is a thing of the past. High-level programming languages offer an alternative to low-level machine code, which makes coding more accessible than ever. Let’s dive into how Golang, a modern higher-level language, matches up to C++, a tried-and-true low-level language. We’ll cover the most important points like which language is more performant, which is easier to learn, which results in cleaner code, and which programming methodologies guide their respective designs.

Quick Sort in Golang

Jun 17, 2021 by Lane Wagner

Quicksort is an efficient sorting algorithm commonly used in production sorting implementations. Like Merge Sort, Quicksort is a divide-and-conquer algorithm. As the name implies, Quicksort is one of the fastest sorting algorithms, but you have to pay attention to detail in your implementation because if you’re not careful, your speed can drop quickly.

How to Write Insertion Sort in Go

Jun 14, 2021 by Lane Wagner

Insertion sort builds a final sorted list one item at a time. It’s much less efficient on large lists than more advanced algorithms like quicksort or merge sort. Insertion sort is a simple algorithm that works just like you would arrange playing cards in your hands. A slice is first split into sorted and unsorted sections, then values from the unsorted section are inserted into the correct position in the sorted section.

Merge Sort in Golang with Examples

Jun 10, 2021 by Lane Wagner

Merge sort is a recursive sorting algorithm and, luckily for us, it’s quite a bit faster than bubble sort. Merge sort is a divide and conquer algorithm.

Writing Bubble Sort in Go from Scratch

Jun 08, 2021 by Lane Wagner

Bubble sort is named for the way elements “bubble up” to the top of the list. Bubble sort repeatedly steps through a slice and compares adjacent elements, swapping them if they are out of order. It continues to loop over the slice until the whole list is completely sorted.

How to Properly Use Defer in Golang

Jun 01, 2021 by Lane Wagner

What is the “defer” keyword in Go? 🔗 In the Go programming language, defer is a keyword that allows developers to delay the execution of a function until the current function returns. What throws some people off is that the deferred function’s arguments are evaluated immediately, but the function itself doesn’t fire until the wrapping function exits.

Comprehensive Guide to Dates and Times in Go

May 17, 2021 by Lane Wagner

Keeping track of time in code has long been every developer’s nightmare. While no language or package manages time perfectly, I think Golang does a pretty good job out-of-the-box. This full tutorial should answer ~90% of the questions you’ll have about time management in Go.

Golang vs Python: Which Language is Best For You?

Apr 29, 2021 by Zulie Rane

These two coding languages duke it out - but who’s the winner? 🔗 In a world where the ability to write any code at all is a tremendous advantage, often the biggest problem coders face is knowing which language to start learning, rather than whether to learn one at all. There are different languages for just about every purpose you could think of. Of those popular coding languages, programmers often face an intense battle of Golang vs Python. (The official name is Go, but the website is Golang.org, so programmers typically refer to it as either interchangeably.)
