How can the string trim method be used in React.js to remove whitespace from the beginning and end of a string?
This code snippet shows a React component that demonstrates the use of the trim() method in JavaScript.
The useState hook is used to define two state variables: text and results. The text variable is initialized with a string that contains extra spaces at the beginning and end of the string.
The myFunction function is called when the button is clicked, and it sets the results state variable to the trimmed version of the text string. The trim() method removes whitespace from both ends of a string.
The trimmed text string is displayed in a pre element, and the trimmed result is displayed in a p element. The useState hook, useEffect hook, and useRef hook are imported from the React library.
Overall, this code snippet provides a simple example of how to use the trim() method to remove extra spaces from a string in React JS.
