## Render with an If/Else Condition
|
||
|
|
||
|
### Method
|
||
|
Inside of the render method of the component, write if/else statements that each have it's own return method that has different JSX. This gives programmers the ability to render different UI according to various conditions.
|
||
|
|
||
|
First, wrap the current return method inside of an if statement and set the condition to check if the variable 'display' is true. Remember, you access state using `this.state`.
|
||
|
|
||
|
### Solution
|
||
|
```react.js
|
||
|
if (this.state.display === true) {
|
||
|
return (
|
||
|
<div>
|
||
|
<button onClick={this.toggleDisplay}>Toggle Display</button>
|
||
|
<h1>Displayed!</h1>
|
||
|
</div>
|
||
|
);
|
||
|
}
|
||
|
```
|
||
|
|
||
|
Next, create an else statement that returns the same JSX **without** the `h1` element.
|
||
|
```react.js
|
||
|
else {
|
||
|
return (
|
||
|
<div>
|
||
|
<button onClick={this.toggleDisplay}>Toggle Display</button>
|
||
|
</div>
|
||
|
)
|
||
|
}
|
||
|
```
