Programming challenge

OMNILYTICS Programming challenge:

Problem Statement:

Write a Web app using React.js to generate four (4) types of printable random objects and store them in a single file, each object will be separated by a ",". These are the 4 objects: alphabetical strings, real numbers, integers, alphanumerics. Sample extracted output:

hisadfnnasd, 126263, assfdgsga12348fas, 13123.123, lizierdjfklaasf, 123192u3kjwekhf, 89181811238,122, nmarcysfa900jkifh , 3.781, 2.11, ....

The output should be 2MB in size. Once file generation is done the output should be available as a link which can be then downloaded by clicking on it. Also, there should be a button on the page so by clicking on this button the total number of each random objects will be displayed.

Note: The backend API must be written using Flask (Python) or Express frameworks. All the communication between frontend and backend MUST be done via these APIs only.

Note: Upload the project in Github and share the link with us.
