#Javascript

Revealed preference is the economics idea that what people do is what people prefer. What #typescript and #javascript developers prefer as their main async pattern is a race... two async methods that both reference and modify the same data structure with no particular guarantees who changes it or reads it first.

All the other patterns have rich abstraction libraries, but this one doesn't.

#typescript #javascript - Because you can assign `undefined` to variables whenever you want it doesn't have to mean "uninitialized", you can use it to mean "Approved for bank loan" or it can mean "true" or it can mean "false" UNLIMITED POWER. Let everyone on your team give it their own personal meaning. Seek out libraries that rely on functions returning undefined & add them to package.json.

Things we will never know while we walk the earth:

- What happens after death
- Universe before big bang
- What the type of that JavaScript event handler argument is

#JavaScript #TypeScript

#TypeScript / #Javascript is just nonstop astonishment.

The error message:
`Cannot read properties of undefined (reading 'readJsonSync')`

The solution:
```

```
