lodash.throttle is a standalone zero-dependency package of just the throttle module. The `lodash` package is a collection of modules one of which is `lodash/throttle`.

You can generally get smaller bundles using `lodash/xyz` modules over the `lodash.xyz` packages because of plugins like:

https://github.com/lodash/babel-plugin-lodash

https://github.com/lodash/lodash-webpack-plugin

Though in the future lodash-webpack-plugin may support `lodash.xyz` packages too.

You should get about the same results using a bundler. Perhaps the lodash.throttle package is for reducing `npm install` time or reducing bloat if you check in your node modules?
