Interesting text editors. Some very old, some very new. Some standalone, some in the cloud.

How to get Node 6.7.0 on Linux

How to get a specific version of Node on Linux, on the example of Node 6.7.0

Written for this question on Stack Overflow: Nodejs - DeprecationWarning process.EventEmitter is deprecated

If you don't have any Node version installed yet but you want to have it installed globally, it may be easiest to install it in /usr/local as /usr/local/bin is likely already present in your PATH.

If you want to install it in addition to a version of Node that is installed on the system, then maybe /opt/node or /opt/node-6.7.0 would be a better place to install it.
