vue中三个点的作用

function sum(...numbers) {  return numbers.reduce((a, b) => a + b, 0);}console.log(sum(1, 2, 3, 4, 5)); // 输出 15

const user1 = { name: 'John', age: 30 };const user2 = { address: '123 Main Street' };const mergedUser = { ...user1, ...user2 };console.log(mergedUser); // 输出 { name: 'John', age: 30, address: '123 Main Street' }

<div v-bind="{ ...props }"></div>
