Prototypal pattern

Let's say I want a provider to request a file

// Create the Provider
const Provider = function(datas) {
    if(!datas || !datas.provider) console.warn('Nope, need a provider')
    const { provider } = datas;
    this.provider = provider;
}

// Attach a function to the Provider
Provider.prototype.requestFile = function(informations) {
    if (informations) {
        console.log(`Le provider est ${this.provider}`);
        return console.log(`Bonjour, je demande le fichier avec ${JSON.stringify(informations)}`);
    }
    return console.warn('Need informations to request the file');
}

// Instanciate the Provider
const P = new Provider({ provider: 'google'})
const M = new Provider({ provider: 'duckduckgo'})

// Use the Provider's requests
P.requestFile({ name: "toto" })
M.requestFile({ name: "toto" })

module.exports = Provider;
