As you can see all node.js packages are installed under the node directory. If ''node-v4.4.5-linux-armv7l/bin'' was added to $PATH in .bashrc after we install nodejs, we won't need to include all other binary directories (installed via npm) to $PATH individually. | |||

Less
Less is a CSS pre-processor, meaning that it extends the CSS language, adding features that allow variables, mixins, functions and many other techniques that allow you to make CSS that is more maintainable, themable and extendable.
Less runs inside Node, in the browser and inside Rhino.

As you can see all node.js packages are installed under the node directory. If node-v4.4.5-linux-armv7l/bin was added to $PATH in .bashrc after we install nodejs, we won't need to include all other binary directories (installed via npm) to $PATH individually.
