Show HN: SuperUtilsPlus – A Modern Alternative to Lodash

Hey HN!

After years of wrestling with Lodash's quirks and bundle size issues, I decided to build something better. SuperUtilsPlus is my attempt at creating the utility library I wish existed.

What makes it different?

TypeScript-first approach: Unlike Lodash's retrofitted types, I built this from the ground up with TypeScript. The type inference actually works the way you'd expect it to.

Sensible defaults: Some of Lodash's decisions always bugged me. Like isObject([]) returning true - arrays aren't objects in my mental model. Or isNumber(NaN) being true when NaN literally stands for "Not a Number". I fixed these footguns.

Modern JavaScript: Built for ES2020+ with proper ESM support. No more weird CommonJS/ESM dance. Actually tree-shakable: You can import from specific modules (super-utils/array, super-utils/object) for optimal bundling. Your users will thank you.

The best parts IMO:

compactNil() - removes only null/undefined, leaves falsy values like 0 and false alone

differenceDeep() - array difference with deep equality (surprisingly useful)

Better random utilities with randomUUID() and randomString()

debounce() that actually works how you expect with proper leading/trailing options

Also genuinely curious - what are your biggest pain points with utility libraries? Did I miss any must-have functions?

Nice work! Reminds me of https://github.com/angus-c/just

Suggestion: add more tests and run some benchmarks

Correct me if I am wrong, but Array factually are JS objects and "[] instanceof Object" is true.

Fair enough if that does not fit your mental model, but I would not use any library that treats facts like opinions.

I agree with the author that it’s almost never what you want. But I agree with you that it’s the reality of the platform, ignoring it will cause its own problems.

I’d surface the footgun rather than trying to pretend it’s not there: isNonArrayObject and isObjectOrArray, or something like that
