I keep seeing posts of some drama with typescript. What happened?
- Why do you have to ship a source map? It compiles to vanilla js
- Not sure what editor, but in neovim (which uses tsserver on my end for LSP) I can either jump to the type declaration or the actual implementation. This is a tooling problem not inherent to typescript
- This doesn’t make any sense. You’d have the same problem with minified js or css etc.
- It means they are forced to use types properly and do the tiniest bit of thinking and planning that results in fewer type errors (think undefined variables and properties, etc)
Not a bad summary, but I take issue with all the points
Edit: The sourcemap comment is relevant to package size and not to final bundle size per the HN comment linked below. Also, the cmd+click critique rings truer now that I know it’s in the context of an installed package. Another critique is build time which is fair enough.
I understand why some hobbyist individuals with small-ish scripts might not see the value, even though I even still disagree there.
The more code and people touching the code, the more value you’ll see.
Thanks :) I didn’t see anyone mention the points made by the svelte guys https://news.ycombinator.com/item?id=35892250 which is a shame since I thought they made better points than the dramatic “type gymnastics” argument haha (i am biased toward type-safety, as long as there is idiomatic, algebraic data types w/ pattern matching)
Overall it sounds like a major change with a few minor/moderate benefits, but it’s their choice and time will tell if it was worth it :P
