helpers4 vs Alternative Libraries
A comparison of helpers4 with popular TypeScript/JavaScript utility libraries.
Overview
Section titled “Overview”| Library | Functions | Size (min+gz) | Tree-shakable | TypeScript | Dependencies | License | Maintained |
|---|---|---|---|---|---|---|---|
| helpers4 | 230 | ~2 KB per pkg | per-package | native | 0 | LGPL-3.0 | Yes |
| radashi | ~130 | ~15 KB | ESM | native | 0 | MIT | Yes |
| radash | ~90 | ~12 KB | ESM | native | 0 | MIT | No (archived) |
| lodash | ~300 | ~70 KB | via lodash-es | @types/lodash |
0 | MIT | Low |
| remeda | ~100 | ~10 KB | ESM | native | 0 | MIT | Yes |
| ramda | ~200 | ~45 KB | limited | @types/ramda |
0 | MIT | Low |
helpers4 vs Radashi
Section titled “helpers4 vs Radashi”Radashi is a general-purpose TypeScript toolkit (~130 functions) and the maintained fork of Radash. The two libraries are complementary.
| helpers4 | radashi | |
|---|---|---|
| Focus | Domain-specific (dates, URLs, semver, observables, promise guards) | Low-level data primitives (sort, group, clone, pick, map) |
| Architecture | Independent @helpers4/* packages per category |
Single radashi package |
| Dependencies | Zero runtime dependencies | Zero dependencies |
Key difference: Radashi provides building blocks for data structures; helpers4 provides ready-made solutions for common domain problems. They’re complementary — see the detailed comparison.
helpers4 vs Radash
Section titled “helpers4 vs Radash”Radash is the predecessor of radashi. It is archived and no longer maintained.
| helpers4 | radash | |
|---|---|---|
| Status | Actively maintained | Archived (no updates) |
| TypeScript | Strict mode, native types | Native types |
| Architecture | Independent packages | Single package |
| Unique to helpers4 | dates, URLs, semver, observables, promise guards | — |
Recommendation: If you’re on radash, migrate to radashi (its maintained fork). If you also need date/URL/version/observable helpers, add helpers4.
helpers4 vs Lodash
Section titled “helpers4 vs Lodash”Lodash is the most popular JS utility library with ~300 functions.
| helpers4 | lodash | |
|---|---|---|
| Size | ~2 KB per category | ~70 KB (full), or install per-function |
| TypeScript | Native strict types | Requires @types/lodash |
| Tree-shaking | Built-in (separate packages) | Requires lodash-es |
| Modern JS | ES2024+ | ES5 compatible |
| Unique to helpers4 | dates, URLs, semver, observables | Deep utilities (_.get with defaults), collection chaining |
Key difference: Lodash is a legacy-compatible, maximalist toolkit. helpers4 is modern, minimal, and focused on gaps that lodash doesn’t cover well (dates, URLs, semver, observables, typed promise guards).
helpers4 vs Remeda
Section titled “helpers4 vs Remeda”Remeda is a TypeScript-first utility library with a focus on data transformation.
| helpers4 | remeda | |
|---|---|---|
| Paradigm | Standard functional | Data-first and data-last (dual API) |
| Pipe support | No built-in pipe | pipe() with type narrowing |
| TypeScript | Strict types | Advanced type inference with pipe |
| Unique to helpers4 | dates, URLs, semver, observables, promise guards | Pipe/compose, advanced type narrowing |
Key difference: Remeda excels at piped data transformations with excellent type inference. helpers4 focuses on domain-specific utilities. They serve different purposes and can be combined.
helpers4 vs Ramda
Section titled “helpers4 vs Ramda”Ramda is a functional programming library focused on currying and composition.
| helpers4 | ramda | |
|---|---|---|
| Paradigm | Pragmatic utility | Purely functional, auto-curried |
| TypeScript | Native strict types | Requires @types/ramda (incomplete) |
| API style | Direct function calls | Auto-curried, point-free |
| Bundle size | ~2 KB per category | ~45 KB |
| Unique to helpers4 | dates, URLs, semver, observables | Lenses, transducers, full FP toolkit |
Key difference: Ramda is for functional programming purists who want auto-currying, lenses, and point-free style. helpers4 is pragmatic and focused on real-world domain utilities.
