Commands Overview

These are useful commands for working with different runtimes (Node.js, and Deno) and managing Deno's caching, modules, and directories.

Benchmark runtimes:
```
hyperfine "node bench.js" "deno run bench.js" --warmup=100 -i
```
This command benchmarks the performance of running the index.js file using Node.js, and Deno. The --warmup=100 flag ensures that each command is warmed up 100 times before measurement, and -i runs the benchmarking interactively.
Deno info command:
```
deno info "https://docs.deno.com/examples/hello-world.ts"
```
This fetches and provides information about the hello-world.ts file from the given URL, including its dependencies and module tree.
Deno run with cache reload:
```
deno run --reload main.ts
```
This runs the main.ts file while forcing a cache reload of the modules to ensure the latest versions are used.
Open Deno's cache:
```
open ~/Library/Caches/deno/
```
Opens the default cache directory on macOS where Deno stores its downloaded modules and files.
Create a new Deno directory:
```
mkdir deno_dir
```
Creates a new directory named deno_dir where you can specify a custom cache location for Deno.
Set a custom Deno directory:
```
export DENO_DIR=./deno_dir/
```
This exports the DENO_DIR environment variable, directing Deno to use the newly created deno_dir as its cache.
Cache specific files:
```
deno cache main.ts
```
Caches the dependencies of the main.ts file for future use, allowing faster execution as it doesn’t have to be downloaded each time.
Add a module with Deno:
```
deno add jsr/......
```
Adds a specific JavaScript or TypeScript module, using Deno's built-in package management capabilities (the full path should replace the jsr/...... part).
Use custom Deno cache directory in commands:
```
$DENO_DIR
DENO_DIR=./deno_dir/ deno main.ts
```
The first command shows the current value of DENO_DIR, and the second command runs the main.ts file using the deno_dir as the custom cache directory.
To install Deno Jupyter, run the following command:

deno jupyter --unstable --install
