React Js String Replace Method

How can the string replace method be used in React.js?

The given code snippet demonstrates the use of the replace() method in React.js to replace a specific string within a text. It starts by importing the necessary modules and initializing the state with the initial text value.

Inside the replaceString function, the replace() method is used to replace the original text with the desired replacement text.

The updated text is then set using the setText function. In the JSX code, the current text value is displayed, and a button is provided to trigger the replacement process when clicked.

How can I perform find and replace operations in React.js?

The given code is a React.js component that implements a find and replace functionality. It uses the useState hook to manage state variables for the text, search term, and replace term.

The text area allows users to input text, and the input fields for search term and replace term are used to specify the text to be found and replaced. When the "Replace" button is clicked, the handleReplace function is called.

It uses the replace method with a regular expression to find all occurrences of the search term (case-insensitive) in the text and replaces them with the replace term.

The updated text is then displayed in the text area, and an alert is shown to indicate a successful replacement.
