Cannot use JSX unless the ‘–jsx’ flag is provided.

The error message “Cannot use JSX unless the ‘–jsx’ flag is provided” is indicating that the TypeScript compiler is not set up to handle JSX syntax, which is used in React.

To resolve this issue, you need to update your TypeScript configuration to include the --jsx flag. Here’s how:

1. Open your tsconfig.json file.
2. Add the following line to the compilerOptions object:

"jsx": "react"

This will tell the TypeScript compiler to handle JSX syntax as React components.

3. Save the changes to your tsconfig.json file.

After making these changes, you should be able to use JSX in your TypeScript files without encountering the error. If you’re still having issues, please provide more details about the error message you’re receiving and your TypeScript configuration.
