React js highlight matching text
React js highlight matching text:In React.js, you can highlight matching text by using the String.prototype.replace() method in combination with regular expressions and JSX. First, you can split the text into an array of words. Then, using map(), iterate over each word and replace the matching portion with a <span> element containing a CSS class for highlighting. Finally, concatenate the modified words and render the result in the JSX. By applying appropriate CSS styles to the highlighted class, you can achieve the desired effect of highlighting matching text.

How can React.js be used to highlight matching text in a user interface?
This React.js code demonstrates how to highlight matching text. The code sets up a React component called App that contains a text container, an input field for searching, and a function for highlighting text.
When the user enters a search term, the handleSearchTermChange function updates the state with the entered value and triggers the highlightText function. The highlightText function uses the replace method with a regular expression to find matches for the search term in the text. It replaces the matches with a <span> element wrapped around the matched text, applying a specified CSS class for highlighting.
The resulting JSX is rendered, and the matching text is visually highlighted using the specified CSS class.
