function getRandomLowercaseLetter() {
    const randomCharCode = Math.floor(Math.random() * 26) + 97; // 97 is ASCII/Unicode code for 'a'
    
    return String.fromCharCode(randomCharCode);
}

function GetRandomLowercaseString(n) {
    let s = "";

    for(let i = 0; i < n; i++ ) {
        s += getRandomLowercaseLetter()
    }
 
    return s;
}

console.log(GetRandomLowercaseString(7));
