Conditional Rendering
Conditional means showing different UI based on a condition — exactly like conditional logic in regular . React doesn't have a special directive for this; you just use inside .
The ternary operator condition ? <A /> : <B /> is the most common pattern. Use it when you need to show one thing or another — two different outcomes based on one condition.
The logical AND operator condition && < /> is cleaner when you only need to show something or nothing. If the condition is false, React nothing. Tip: make sure the condition is a boolean — {count && <Badge />} will print '0' when count is 0.
For complex conditions with many branches, pull the logic out into a or a separate if/else block above the return ment. Keep the itself readable — move complexity up, not into the markup.
