I am building a React application in Typescript. In my React application, my Typescript code need to call a JavaScript function.

so I try the answer from here Call external Javascript function from react typescript components And I did

1. Create a Myutil.js file which contains a JS function:

   export default { function myTestFunction(arg1, arg2) { ... return 1; } };

2. In my Typscript code I call the function like let returnValue = myTestFunction("abc", "def");

But when I compile it, I get error saying

myutil.js(2,14): error TS1005: Build:':' expected.

And column 14 of line 2 is the beginning of the function name myTestFunction

 function myTestFunction
          ^
          |
         14

Can you please tell me what am I missing?

Thank you.
