The James Webb Space Telescope (JWST) is transforming our view of galaxy formation and evolution in the young Universe. I will provide an overview of the latest results from the PRIMER survey, the largest JWST Cycle-1 “Galaxies” programme which, in combination with other public JWST imaging, is now enabling us to chart the early growth of the galaxy population back to within ~300 million years of the Big Bang. Specifically, I will present and discuss the first robust determination of the evolving galaxy luminosity function extending out to redshifts z~13, as well as new measurements of the galaxy stellar mass function reaching out to z~9. I will then attempt to interpret these results in the context of our current understanding of the evolving dark matter halo mass function and the efficiency with which galaxies are able to convert their baryons into stars. Finally, I will discuss the prospects for future progress with JWST and with the Atacama Large Millimeter Array (ALMA), including the possibility of uncovering the emergence of the first galaxies.
