jspm or npm to install packages? : <p>I'm new to jspm, transitioning from npm-only. I have one fundamental question. I have some dependencies in the package.json, and I runned jspm init, which created a nice jspm config.js file. My question is, what it the point of installing these packages from jspm (via <code>jspm install ...</code>)? Why not just install them through npm?</p>

<p>More specifically, in my package.json, what's the difference between putting these packages inside <code>dependencies: {} vs inside jspm.dependencies: {}</code></p>
