A designer hands you a mockup that violates color contrast accessibility standards. What is the professional course of action?

Question 2

What does 'trunk-based development' promote in a professional front-end team context?

Automated tooling removes subjective style debates and enforces standards consistently on every commit.

Question 4

What is the primary professional purpose of a post-mortem after a front-end production incident?

Accepted Answer

To identify root causes and systemic improvements to prevent recurrence

Answer

Blameless post-mortems focus on process improvements rather than individual fault, creating a safer learning culture.

Question 5

As soon as the risk is identified, with clear explanation and options

Answer

Early risk communication gives stakeholders time to adjust scope, timeline, or resources before impact becomes unavoidable.
