I Built a Reactive Compiler for JavaScript — Here's Where It Broke
📰 Dev.to · Maryan Mats
Learn from a developer's experience building a reactive compiler for JavaScript and the challenges they faced with reactive variables and compiler theory
Action Steps
- Explore compiler theory to understand how reactive variables can be implemented
- Use TypeScript hacks to handle hydration nightmares and specification-by-example gaps
- Analyze when a reactive variable should behave like an object and when like a value
- Implement a reactive compiler for JavaScript to test and refine your understanding
- Debug and troubleshoot common issues that arise during the compilation process
