I think the reason leetcode problems are still popular is because they test whether a candidate is willing to work hard (‘grind’) on problems that don’t even matter. A lot like what actually goes on at a FAANG company.

Hard disagree. At FAANG companies, working on problems that "don't matter" is exactly how you get a "Meets Some" or worse at your next perf review. These companies are obsessed with measurable impact - you need to show clear business value, user metrics, or revenue impact. Spend 6 months grinding on irrelevant work and you'll be on a PIP in a blink of an eye

Seeing Primeagen featured on homepage is concerning - a financial database requiring absolute reliability doesn't align with someone whose brand is built on chaos and controversy.

Hey! Not sure how modern your codebase is, but you can consider the following tsconfig settings:

- rewriteRelativeImportExtensions: this will allow you to write `import foo from './foo.ts'` and have tsc transform it to `import foo from './foo.js'`

- erasableSyntaxOnly: this will error on non "erasable" syntax, that is, TypeScript code that has a runtime output (e.g. enums)

With these two settings enabled, you'd be able to run TypeScript code directly with Node: `node src/index.ts`, and cut boot up time substantially

While `rewriteRelativeImportExtensions` works for frontend applications, it has a significant limitation: it doesn't fix declaration files (.d.ts), which is problematic when developing libraries or public packages.

I created a small tool to address ESM + TypeScript issues that the tsc doesn't handle: https://github.com/2BAD/tsfix
