这是一个简单的单线

const randomElement = array[Math.floor(Math.random() * array.length)];

例

const months = ["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"];

const randomMonth = months[Math.floor(Math.random() * months.length)];



console.log("random month =>", randomMonth);
