Select Value Attributes from Array in React

Let's again store the list items in an array:

function App() {
	const texts = ['text1', 'text2', 'text3', 'text4'];
	const [value, setValue] = useState('');
	
	...
}

Let's use this array to form option tags, adding the values of the array elements as value attributes:

function App() {
	const texts = ['text1', 'text2', 'text3', 'text4'];
	const [value, setValue] = useState('');
	
	const options = texts.map((text, index) => {
		return <option key={index} value={index}>{text}</option>;
	});
	
	...
}

Using the generated tags, we will create a drop-down list:

return <div>
	<select value={value} onChange={event => setValue(event.target.value)}>
		{options}
	</select>
</div>;

Let's display the number of the selected item in the paragraph:

return <div>
	<select value={value} onChange={event => setValue(event.target.value)}>
		{options}
	</select>
	<p>
		your choice: {value}
	</p>
</div>;

Now let's display the text of the selected item using its number and an array of texts:

return <div>
	<select value={value} onChange={event => setValue(event.target.value)}>
		{options}
	</select>
	<p>
		your choice: {texts[value]}
	</p>
</div>;

Let's put it all together and get the following code:

function App() {
	const texts = ['text1', 'text2', 'text3', 'text4'];
	const [value, setValue] = useState('');
	
	const options = texts.map((text, index) => {
		return <option key={index} value={index}>{text}</option>;
	});
	
	return <div>
		<select value={value} onChange={event => setValue(event.target.value)}>
			{options}
		</select>
		<p>
			your choice: {texts[value]}
		</p>
	</div>;
}
