(Free climbers use ropes, but only to arrest falls, not to climb up. Free soloers like Alex Honnold don't even use that protection, though that's very rare and incredibly dangerous. This is "aid climbing" with ascenders. It does have dangers of its own: protection points can fail, and she's wearing a helmet because rocks do fall.)
*edit - should have written jumaring
In this specific case I'm pretty sure that the two adults took the leads and the girl followed jumaring behind.
It looks like she led the first pitch of 5.7 free climbing and an A0 (easy aid climbing) bolt ladder. She otherwise followed and cleaned/removed gear for her father and a family friend in the party, who appear to be experienced. They planned for 4 days, but completed in 5. My understanding is this is a standard pace for amateurs and they were even outpacing other parties. The primary difficulties for a kid, besides the technical climbing, are maintaining focus for 5 days on the wall 1000s of feet up and sleeping on a small ledge, and carrying a large amount of heavy gear, relative to bodyweight.

Some people seem a different (superior) species.
This is a lot of training and committed parents. I'm doing a lot of aid climbing myself and anyone could be good at aid climbing if enough training and commitment is put inside it.
I'm still impressed, even with ascending devices. For being 10 years old, that shows a lot of patience and deliberation.
The majority of the routes are not bolted (see the breakdown of climb by type on this page): https://www.mountainproject.com/area/105833388/yosemite-vall...
They climbed The Nose, which seems to be a mix of trad (traditional, no fixed holds) and aid (placing temporary protection, then using gear to climb up to the protection, then placing protection, etc.) climbing - more on the different types of climbing here: http://www.alpineinstitute.com/articles/expert-tips/rock-cli....

You can see in the map of the route that some belay stations are bolted, and in fact the original ascent did use bolts - https://en.wikipedia.org/wiki/The_Nose_(El_Capitan).
> If it's dangerous it should be unlawful
The mountains, the oceans, and the deserts seem to be the last refuges of freedom. I hope that doesn't change.
The closest thing might be Child Endangerment (or similar depending on jurisdiction) but I'd argue with the safety gear she had on it wouldn't pass the "reasonable person" test. Which is to say a reasonable person wouldn't find it unsafe to climb El Capitan with full safety gear, an experienced adult climber, and experience climbing smaller peaks herself.
