Section 1
The premise
Strict TS migrations stall because the error count is overwhelming; LLMs batch fixes by category.
What AI does well here
- Categorize errors (implicit any, null checks, index signatures) and fix per batch
- Generate type guards and narrow utility types
What AI cannot do
- Decide between as-cast escape hatches and proper types
- Own the rollout schedule
Understanding "AI and TypeScript strict mode migration" in practice: AI-assisted coding shifts work from syntax recall to design thinking — models handle boilerplate so you focus on architecture. Migrate a JS/loose-TS codebase to strict TypeScript with LLM help — and knowing how to apply this gives you a concrete advantage.
- Apply typescript in your ai-coding workflow to get better results
- Apply strict mode in your ai-coding workflow to get better results
- Apply migration in your ai-coding workflow to get better results
- 1Use AI to generate unit tests for an existing function
- 2Ask AI to refactor a messy function and explain the changes
- 3Have AI suggest a code review for a recent pull request
