Oops! Error in JSX React/TypeScript Context Provider: SyntaxError - Unexpected token. Make sure to check for

Encountering a SyntaxError when incorporating a Context Provider in my React TypeScript project. The error points to an unexpected token and a missing comma within the JSX.

export const MapProvider: React.FC<React.PropsWithChildren<{}>> = ({ children }) => {
    // ... 

    return (
        <MapContext.Provider value={contextValue}>
            {children}
        </MapContext.Provider>
    );
};

I've double-checked my code for syntax errors, confirmed the correct usage of brackets and commas in the JSX return statement, reviewed the context setup, and sought solutions in online discussions.

When working with React and TypeScript, make sure to save your components with a .tsx file extension. This lets the TypeScript compiler know that you will be using JSX syntax for writing HTML-like code within your JavaScript files, allowing for type checking and other advantages in React development.

Additionally, don't forget to configure your tsconfig file to support JSX:

{
  "compilerOptions": {
    "jsx": "react"
  }
}

For more information on using JSX with TypeScript, check out this link: https://www.typescriptlang.org/docs/handbook/jsx.html
