What happens when deno removes golang?

Recently, Ryan Dahl, the founder of deno, announced on Twitter that golang will be removed from deno, which also caused widespread discussion and attention. Some people think this decision is very wise, but others are worried. In this article, we take a look at the reasons for this decision and its possible impact.

First, let’s briefly introduce deno. It is an emerging JavaScript runtime environment developed by Ryan Dahl, the founder of Node.js, aiming to provide a safer and simpler JavaScript runtime environment. Unlike Node.js, deno uses the V8 engine, supports TypeScript, and can write plug-ins in a variety of programming languages. In addition, it has an interesting feature: by default, it does not allow access to sensitive information such as file systems and environment variables, and can only be accessed with explicit authorization, thus providing higher security.

The decision to remove golang is actually related to this security mechanism. In early versions, deno used golang to perform some management tasks. But in the latest version of deno, Ryan Dahl has removed these dependencies and instead uses the Rust language to implement these functions. There was a reason for this decision: Ryan Dahl believed that using golang would increase the complexity and security risks of deno because it would require adding an additional external dependency. Rust has been proven to be a very safe language, and its design goal is to avoid memory safety issues.

Of course, this decision also caused some people to worry. Some people believe that removing golang may make deno's performance degrade in some specific areas, because golang is a very fast programming language. In addition, some plug-ins also rely on golang to implement some functions, such as deployment and compilation.

Despite these concerns, Ryan Dahl has a solution: deno will support plug-ins written in other languages, and plans to support WebAssembly in the future. This means that while removing golang may cause some inconvenience, it will not have a significant impact on deno's capabilities.

In short, it is a wise decision for deno to remove golang, which will improve the security and simplicity of deno. Although this may cause some short-term inconvenience, deno's future development will be more stable and reliable.
