Currently, I am working on a modernisation project in which the team are creating new applications, as well as updating old applications (some are older than me😄) with new modern technologies, such as Angular, NodeJS etc.
We realised that some of the new technologies we are using are already out of date, for example, we are using Node 6.9.1 (current LTS version is 10.16.3). Along with other packages being behind their most recent version the question came up of "When does our application become a legacy application?".
So I thought I would put this question out into the community to get your thoughts.
