🚀Que fait la fonction lol ?

 const lol = function(strs) {
    let prefix = strs.reduce((acc, str) => str.length < acc.length ? str : acc);
    
    for (let str of strs) {
        while (str.slice(0, prefix.length) != prefix) {
            prefix = prefix.slice(0, -1);
        }
    }
    return prefix;
};
let res = lol(["dupont","dupond","dupone","dupot"]);

🆘console.log(res);
