What do weeds do differently than other plants that lets them grow so quickly?

Question

Edit: The weed lobby is alive and well in the comments! Just kidding. Appreciate the responses.

But my question still sort of stands. Take away the pejorative label “weed”—what allows these plants to perform better than the other ones?

Weeds are just plants you didn’t mean to grow. All plants compete for water, light, and nutrients. Stronger plants push everything else out of the way and steal the resources.
