I stand by my claim that Rust is worthy of consideration even if you’re just starting out as a developer. Rust also does better than Go, Java, and Python. Rust can match C or C++ in speed, if not surpass them. That’s because of its high security standards - it’s harder to make mistakes - and its low-level code. That means developers see fewer serious security issues and waste less time debugging. But with Rust, strong memory safety features preclude these kinds of mistakes. This can bring about buffer overruns and stack overflow vulnerabilities.

In C++, developers have free access to memory.
Its focus on security is what convinced me of its merits. Rust is safe, secure, and high-performingĪs a longtime C++ programmer, I had to come around to Rust.
Even if you’re not looking for a new job, it’s always a good idea to keep your interview prep skills sharp. Designed to teach you the essential patterns underlying coding interview questions, this course provides hands-on practice while saving you from drilling endless problem sets. If you’re already familiar with Go or have the programming background to pick it up quickly, check out the new course Grokking Coding Interview Patterns in Go. After finishing the four modules, you’ll be able to write efficient and practical applications with Go. It also offers brain teasers and puzzles to refine your critical thinking and problem-solving skills. I touted this Skill Path in last week’s newsletter, too, because it teaches both basic and advanced concepts such as error handling, networking, templating, and concurrency. If I’ve persuaded you to give Go a look, consider checking out the Skill Path Golang for Programmers on Educative. As a compiled language, like C and C++, Go is faster than Python and more efficient than Java.Go executes native code, but it runs in a small runtime, enabling efficient and fast garbage collection.(Memory safety is a feature I love about Rust, too, as I’ll discuss later.) To avoid the memory leaks of C++, Go’s creators took the job of memory management away from developers.On top of supporting concurrency, Go offers other goodies. In fact, for developers, concurrency in Go is easier to implement and faster than in any other major programming language. It was the first programming language to embrace concurrency from the start. The multithreading models of older languages had to be retrofitted to exploit the power of the new hardware. Now they had multiple processors at their disposal to handle tasks simultaneously. If you play music while surfing the web on a single-processor machine, your OS will divide time between those tasks.Įventually, we started seeing hyperthreading, and after that, multiple cores in the same processors. Back then, the biggest innovation in operating systems working on single processors was time slicing, in which each thread got its own tiny sliver of time. Other programming languages were developed before multi-core processors and hyperthreading. Go’s built-in support for concurrency separates it from other popular programming languages.
They were among the most wanted technologies in last year’s Stack Overflow Developer Survey, and each has captured my personal curiosity for reasons I will explain. These languages remain as in demand as ever.īut I’m going to make the case for three relative newcomers that developers who want to position for the future should keep on their watchlists: Go, Rust, and Kotlin. Perennial favorites like Python and JavaScript might be on your radar. You can look at rankings of languages’ popularity, but that still leaves many choices.

With over seven months remaining before the calendar changes again, now’s a good time to take stock of our progress toward personal and professional goals. What are your plans for the rest of 2023?
