That example makes a lot of sense once you realize how JSX works in SolidJS (and its very different from React):

1. The function is called only once at component construction, and never again. Unlike React, it is _not_ called for every render.

2. Every expression in `{}` is compiled to a thunk function - not to a direct JS expression.

For example, the expression

   <>{props.count * 2}</>

compiles to

    memo(() => props.count * 2)

Another interesting bit - as the article above rightfully points out, `useState` and `useMemo` are signals. The main difference is that you have to track and specify your dependencies manually, whereas Solid auto-tracks dependencies based on their usage while the computation runs.
