Actually there are a couple of projects which realize the conditional part as React component. But they are all confronted with the following problem:
<If condition={obj}>
<div>{obj.name}<div>
</If>
The code inside the <If>
statement would get evaluated nonetheless, even if obj
is false
or undefined
. Hence the compilation step, which is the only elegant way to solve this.
Read also Why Transform. This reason should probably be made more prominent, like putting it into the intro section. So let's keep this issue open until it is better documented.
from jsx-control-statements.
A compile-step advantage I see is being able to convert each="item"
into a variable reference, not possible with runtime.
from jsx-control-statements.
Pros
- Conditionals are not flawed
- For statements with variable reference are made possible
- There's no penalty on the runtime performance
- It works exactly as JSX is supposed to work: Plain syntactic sugar
Cons
- Requires Babel (6)
- Penalty on build time performance
from jsx-control-statements.
Closing in favor of #39
from jsx-control-statements.
