TypeScript Regulatory Compliance & Legal Framework 4

Question 1

A TypeScript library uses the LGPL license. Under what condition can a proprietary application link to it without being required to open-source the application?

Accepted Answer

When the application links dynamically and allows users to replace the LGPL library

Answer

The LGPL allows proprietary applications to link to the library provided the end user can replace the LGPL component, typically satisfied by dynamic linking.

Question 2

Which TypeScript pattern enforces data minimization (collecting only necessary data) at the type level?

Accepted Answer

Using `Pick<T, K>` to expose only the fields needed for each operation

Answer

The `Pick` utility type creates a type with only the specified fields, forcing functions to declare exactly which data they need and preventing access to unneeded fields.

Question 3

Under the Americans with Disabilities Act (ADA) as applied to web applications, a TypeScript-built web app must generally:

Accepted Answer

Meet WCAG accessibility guidelines to be usable by people with disabilities

Answer

US courts have applied the ADA to websites, generally requiring conformance with WCAG 2.1 Level AA so that users with disabilities have equal access.

Question 4

A software contractor ships TypeScript code with no written agreement about IP ownership. Who typically owns the copyright in the US?

Accepted Answer

The contractor owns it unless a written work-for-hire agreement or IP assignment exists

Answer

Under US copyright law, the author (contractor) owns the work by default; a work-for-hire arrangement or explicit IP assignment agreement is required to transfer ownership to the client.

Question 5

Which export control regulation may apply when a US company ships a TypeScript cryptography library to users in sanctioned countries?

Accepted Answer

EAR (Export Administration Regulations)

Answer

The EAR controls exports of dual-use goods and technology, including encryption software, and can restrict distribution to certain countries or end users.
