monet.js
Adds functional monadic types like Maybe, Either, Validation, etc., to JavaScript so you can handle nulls and errors without try/catch.
- •You need to safely chain operations on values that might be null/undefined.
- •You want explicit error handling without throwing exceptions.
- •You are building data pipelines where each step may fail and you want to keep the code readable.
```js
const { Maybe, Either } = require('monet');
function parseJson(str) {
return Maybe.fromNull(str)
.map(JSON.parse) // may throw – wrap in Try later if needed
.cata(
() => Either.left('invalid JSON'),
obj => Either.right(obj)
);
}
const payload = '{"age":30}';
const result = parseJson(payload)
.flatMap(data => data.age >= 18 ? Either.right('adult') : Either.left('minor'));
result.cata(
err => console.error('Error:', err),
msg => console.log('Success:', msg)
);
