str-fns

A collection of type-safe string functions written in pure JavaScript + JSDoc.

Why str-fns

• I copy and paste useful functions from my notepad for every project using TypeScript/JavaScript. This library is a library of those functions.
• I need some useful functions to deal with string types in my projects. This library is a collection of those functions with type-safety.

Why JavaScript + JSDoc / Why not TypeScript

As Svelte team said, TypeScript is a great tool for library authors, but not for library users.
One of the reasons is that it is hard to jump to the definition of a function when using TypeScript.
I want to make it easy to jump to the definition of a function, so I use JavaScript.
Don't worry, I use JSDoc to make it type-safe.
