Unless you are involved with the Node.JS ecosystem [1][2] not knowing what those projects are is irrelevant, at least it is for me and I still know what they are. I will make an assumption and say that you work with a different technology and/or in a different field that doesn't involves web development, in this case there is no need to think that, because you do not know something outside the focus of your work, your career will be affected.
