Installing Deno.js

Run the official Deno installer:

curl -fsSL https://deno.land/install.sh | sh
source ~/.bashrc

Verify installation:

deno --version

---

Installing Bun.js

Run the official Bun installer:

curl -fsSL https://bun.sh/install | bash
source ~/.bashrc

Verify installation:

bun --version

Notes

• Deno.js installation automatically sets the environment variables, so we only need to reload the shell (source ~/.bashrc).
• Bun.js may have compatibility issues on proot Ubuntu. If you encounter issues, check the latest discussions in Bun’s GitHub repository.
