How to trigger a typescript function from an external JavaScript function

In my project, I have a TypeScript file called 'abc.ts' which includes a method named 'ScanCode()'. Additionally, I have a separate JavaScript file named "sample.js" with a method titled foo(). My goal is to invoke the ScanCode method from the TypeScript file within the foo method of the sample.js file.

I attempted to import the TypeScript file into JavaScript, however, it seems that the 'import' function is not recognized.

To convert your typescript file into JavaScript, you'll need to compile it, or consider using a tool like webpack for importing. One simple method of accessing your typescript function is by making it global.
