The JWST looks at light which has been travelling for a long time. The only special thing about it, compared to other telescopes (or even your eyes), is the range of frequencies it's looking at - the longer light travels, the lower the frequency becomes (due to the expansion of the universe).

So it's the same basic phenomenon - information has a max speed, so you're always interacting with the past state of any object.
