Fixed Issues

typescript:S1854 - Remove this useless assignment to variable "dataString". • MAJOR • View issue

Location: data/static/codefixes/dbSchemaChallenge_1.ts:7

Why is this an issue?

Dead stores refer to assignments made to local variables that are subsequently never used or immediately overwritten. Such assignments are unnecessary and don’t contribute to the functionality or clarity of the code. They may even negatively impact performance. Removing them enhances code cleanliness and readability. Even if the unnecessary operations do not do any harm in terms of the program’s correctness, they are - at best - a waste of computing resources.

What changed

Removes the unused assignment to the local variable 'dataString'. The variable was assigned the result of JSON.stringify(products) but was never subsequently read or used, making it a dead store. By deleting this line entirely, the useless assignment is eliminated, resolving the dead store code smell.
