Write a function that

• takes in an array of filepaths as parameter
• return a list of unique emails that don't belong to sync.com Note: The filepaths and paths to actual files, for example: /home/surya/emailfiles/file1.txt and /home/surya/emailfiles/file2.txt. And these files contain email addresses. One address per line.

test

The findUniqueEmails function uses a set to store final result of unique email addresses. Using a set ensures that duplicate email addresses are automatically eliminated.

The function uses asynchronous iteration to process file content line by line. Asynchronous iteration allows the function to handle large files without blocking, will result in improving performance.

By using asynchronous iteration and concurrency with Promise.allSettled, the function can process multiple files concurrently.

If there are any issues during this process, such as invalid email formats or file not found errors, it collect these errors for later handling.

To run this code, you'll need the following:

Download and install Node.js > v18.13.0 from the official website (https://nodejs.org/en).

Use command below to install dependencies

npm install

Runs the TypeScript compiler (tsc) to compile the TypeScript files into JavaScript files.

Performs the following tasks:

1. Removes the existing build directory.
2. Builds the project by executing the build script.
3. Starts the application in production mode by running the compiled index.js file with gc tracing enabled.

Starts the application in development mode using nodemon, which automatically restarts the server when changes are detected in the source files.

Executes the tests written in TypeScript located in the test directory. It requires ts-node to compile TypeScript files on the fly before running the tests.
