There you have it: the top programming language trends to expect to play out over the coming year. If you had to choose the single most important language to learn for the long term, C would be a good choice. And given that C has now been around for over a half-century - which makes it nearly twice as old as languages like Python and Java - C stands out as a language that will probably retain its importance to software development for decades to come. It's now in ninth place, which is a slight decrease from last year, but that still puts it ahead of languages such as PHP, Go, and Swift.Īssembly language's popularity may also reflect the growing adoption of specialized hardware, like internet of things (IoT) devices, that may require developers to write assembly code to access functionality that's not supported by higher-level languages on those devices.Ĭ's not quite as popular as Python, but it's close.

In recent years there has been a slow but steady increase in the popularity of assembly language.Assembly language (a generic category that could include multiple specific languages) first entered the top 10 list of most popular languages in 2016. Using Rust won't guarantee protection against attacks, but it's one step developers can take to make their software a bit more secure. But Rust has a strong following of devoted users and it's the 'most loved' programming language according to Stack Overflow, even if it's not the most commonly used. Rust, the open source language with a focus on security, remains relatively unpopular, with a twentieth-place ranking on the TIOBE Index.
