1. As Package Manager (Installing, updating, and managing dependencies)

This aspect is crucial since package managers are a core part of modern JavaScript development workflows. Evaluating their performance in handling dependencies means conducting tests for:

1a. Clean Install Time for All Dependencies in package.json

• Install dependencies for a project with 100 dependencies (IT, MU, CU)
• Install dependencies for a project with 1000 dependencies (IT, MU, CU)

1b. Install Time for a Single Dependency

• Install a popular dependency like lodash (IT, MU, CU)
• Install a dependency with many sub-dependencies (IT, MU, CU)

1c. Update Dependencies

• Update all dependencies to their latest versions (IT, MU, CU)
• Update a single dependency to its latest version (IT, MU, CU)

1d. Remove a Dependency

• Remove a dependency from a project with 100 dependencies (IT, MU)
• Remove a dependency with many sub-dependencies (IT, MU)

1e. Fresh start a project

• Create a Next.js app (IT, MU, CU)
• Create an Angular app (IT, MU, CU)
• Create a Svelte app (IT, MU, CU)

2. As an HTTP Server (Serving HTTP requests)

Both runtimes can be used to create an HTTP server. Analyzing and comparing this aspect is pretty important.
