How can I implement a find and replace functionality for text within a textarea using Reactjs?
The provided code is a React.js component that allows users to find and replace text in a textarea element. It uses React's useState hook to manage the state of the text, findValue, replaceValue, and replacements.
When the "Replace" button is clicked, the handleReplace function is called. It first checks if the findValue is not empty. If it's empty, an alert is shown to the user. Otherwise, it replaces all occurrences of findValue with replaceValue in the text using the replaceAll method and updates the state variables accordingly.
The component renders a textarea, two input fields for find and replace values, and a "Replace" button. The number of replacements is displayed below the button.
