If you have two slits very close to one another, it stands to reason that any individual quantum of energy will go through either one slit or the other. Like many others, you might think that the reason light produces this interference pattern is because you have lots of different quanta of light — photons — all going through the various slits together, and interfering with one another. So you take a different set of quantum objects, like electrons, and fire them at the double slit. Sure, you get an interference pattern, but now you come up with a brilliant tweak: you fire the electrons one-at-a-time through the slits. With each new electron, you record a new data point for where it landed.
