array.splice(start[, deleteCount[, item1[, item2[, ...]]]])

splice() 方法通过删除或替换现有元素或者原地添加新的元素来修改数组，并以数组形式返回被修改的内容。
此方法会改变原数组。

const months = ['Jan', 'March', 'April', 'June'];

// remove last one item
months.splice(months.length - 1, 1);
// ["June"]

console.log(months);
// ["Jan", "March", "April"]

const months = ['Jan', 'March', 'April', 'June'];

// remove last one item
months.pop();
// "June"

console.log(months);
// ["Jan", "March", "April"]
