Why do Kangaroos jump instead of walk?

This might be a really weird question, but why do Kangaroos jump instead of walk?

As a human jumping takes a lot more energy than jumping, so it must be something biological, but they are like the only animal family that does that (I’m sure there are more kangaroo-like animals I don’t know about)?

Edit – After seeing a few comments, this post isn’t about why the evolved to do so (even though it is an interesting question), I was asking what is the anatomical reasoning for it.

Because their legs work like springs. The kangaroo uses less enery when it jumps because it stores the energy from landing and uses 8t for the next jump.
