Well, what I mean is, normal "coding" tends to look like this:
It's exceptionally complicated and getting even a small thing to happen onscreen, like an object moving when you hit keys, takes a long time and a ton of typing.
Fusion, on the other hand, looks like this:
Most of what is in there is done via clicking, not typing. The checkmarks you see there are the core of it, representing an interaction between the "event" on the left, and an object at the top. Needless to say there's still alot going on here, but... well, I'll put it this way, if you gave me just 2 hours, I could recreate Space Invaders on here. With normal "coding" it'd take about a million years. Even for just small things... if I had the ship at the bottom, and I wanted it to fire a shot upwards, it'd be this long barrage of code when done the traditional way. In here, it's just "spawn object, set object's speed and direction to this" and that's it. Takes less than a minute to create a simple interaction like that. It's marketed as a tool for game creation where "no prior programming knowledge is necessary".
It actually originally showed up in the 90s, under the name Klik'n'Play. Even kids could make games on that (though obviously they'd usually make bad ones), and that was back in the 90s when computers werent user friendly. Though it's obviously come a loooooooooong way since then.
So, yeah, often you hear "it's not really coding" from programmers, that sort of thing. Despite the sheer versatility of it.
