Example

A sample of what this objective produces. Your result is generated for your inputs.

export function slugify(text) {
  return String(text)
    .toLowerCase()
    .trim()
    .replace(/[^a-z0-9]+/g, "-")
    .replace(/^-+|-+$/g, "");
}

// slugify("  Hello, World!  ")     -> "hello-world"
// slugify("Node.js & TypeScript")  -> "node-js-typescript"
