Deno improves npm security via sandboxed architecture

Deno offers a more secure approach to using npm packages compared to Node.js by utilizing a sandboxed architecture and an opt-in permission model.

While npm provides vast accessibility for the JavaScript community, Node.js applications are often susceptible to supply chain attacks because dependencies typically have unfettered access to the filesystem, network, and environment variables. In contrast, Deno runs code in a sandbox where access to system resources must be explicitly granted via command line flags or runtime prompts. This security model, similar to modern web browsers, aims to mitigate risks such as shell injection, malware installation, and unauthorized data theft.
