useMatch
is a custom React Hook that allows you to match a single character or a string from an array of strings.
To use useMatch
, import it from the react-use-match
library:
import useMatch from 'react-use-match';
Next, call useMatch
with an array of strings and the character or string you want to match:
const [isMatch, matchIndex] = useMatch(['apple', 'banana', 'orange'], 'a');
isMatch
will return a boolean indicating whether or not the character or string was found in the array. matchIndex
will return the index of the first match it finds.
import React from 'react';
import useMatch from 'react-use-match';
function App() {
const fruits = ['apple', 'banana', 'orange'];
const [isMatch, matchIndex] = useMatch(fruits, 'a');
return (
<div>
<h1>Fruit Matching</h1>
<ul>
{fruits.map((fruit, index) => (
<li key={index}>
{index === matchIndex && isMatch ? (
<strong>{fruit}</strong>
) : (
fruit
)}
</li>
))}
</ul>
</div>
);
}
export default App;
This will display a list of fruits and highlight the first fruit that contains the letter 'a'.
useMatch
is a simple and useful utility that can save you time and effort when searching through arrays of strings in your React projects. Try it out and see how it can help you!
