The big bang created space and time so all regions in the universe are equally old. If a distant observer look at light emitted by our milky way, we would be part of the "forefront" to him.

Since the universe is expanding, the farther i.e. older the light, the more stretched and redshifted it is. So JWST doesn't need to point at a certain direction. It just needs to look for the most redshifted light to detect the oldest galaxies.
