How to remove accent marks in a string using vanilla Javascript

In JS is quite of easy to replace chars by using str.replace for example, but, what happens when you want to remove accent marks?

I'm a native Spanish speaker, so this could be helpful if you need to handle some Spanish words.

This tiny post will build an example on how to make a slug from a Spanish sentences strings.

The code

// Input example
const spanishSentences = [
  "teléfono",
  "árbol",
  "colibrí",
  "cómpramelo",
  "Mandó una carta",
  "Qué grande es ese perro"
];

// Function definition
function createSlug(input){
  return input
    .toLowerCase()
    .trim()
    .replace(/[\s_-]+/g, "-")
    .replace(/^-+|-+$/g, "")
    .normalize("NFD")
    .replace(/[\u0300-\u036f]/g, "");
}

// Usage
const output = spanishSentences.map(createSlug);
console.log(output);
// Output:
/*
[
  "telefono", 
  "arbol", 
  "colibri", 
  "compramelo", 
  "mando-una-carta", 
  "que-grande-es-ese-perro"
]
*/

And that's it, happy coding!
