deverything

Everything you constantly need for development (and probably still copy-pasting from other projects)

The promise:

• ✅ 1 package: say goodbye to lodash, faker, and the other package you don't recall the name of.
• ⭕ 0 dependencies: keep it simple and lightweight.
• 🏆 Pick the best: the code is minimal and uses the best practices for max performance.
• 👪🏼 Typescript: use it, support it and export it.
• 🌊 Intuitive: favour always the most intuitive API and common usage, never throw error unless asked to.
• 🙈 Semantic: use simple function names that are easy to remember, no complicated options.

Contributions always welcome!

Validators

• isArray()
• isBoolean()
