Create slug from string in Javascript

slugify.js

function string_to_slug (str) {
    str = str.replace(/^\s+|\s+$/g, ''); // trim
    str = str.toLowerCase();
  
    // remove accents, swap ñ for n, etc
    var from = "àáäâèéëêìíïîòóöôùúüûñç·/_,:;";
    var to   = "aaaaeeeeiiiioooouuuunc------";
    for (var i=0, l=from.length ; i<l ; i++) {
        str = str.replace(new RegExp(from.charAt(i), 'g'), to.charAt(i));
    }

    str = str.replace(/[^a-z0-9 -]/g, '') // remove invalid chars
        .replace(/\s+/g, '-') // collapse whitespace and replace by -
        .replace(/-+/g, '-'); // collapse dashes

    return str;
}

export const convertToSlug = (...args: (string | number)[]): string => {
    const value = args.join(' ')

    return value
        .normalize('NFD') // split an accented letter in the base letter and the accent
        .replace(/[\u0300-\u036f]/g, '') // remove all previously split accents
        .toLowerCase()
        .trim()
        .replace(/[^a-z0-9 ]/g, '') // remove all chars not letters, numbers, and spaces (to be replaced)
        .replace(/\s+/g, '-') // separator
