JavaScript规定

整功能模块注释
/**
 *   列表筛选
 *   @param {Array} xxxxx              保存所选省份
 *   @param {String} xxxxxxxxxx        保存所选年代
 *   @method xxxx                      保存所选部分,用于筛选
 *   @method xxxx                      删除筛选中所选条件
 *   ......
 */
整功能模块内部小功能代码注释也需要写
// 列表分页
xxxx
// 重置筛选条件
xxxx
let searchVal = '';
function getUserInfo() {}
const name = 'yuci';
const userArr = ['a', 'b', 'c'];
if (i === 0) {
    // do
}
for (let i = 0, len = arr.length; i < len; i++) {
    // do
}

if (i === 0) {
    // do
} else {
    // do
}
try {
    // do
} catch {
    // do
}
switch (dataSort) {
    // do
}
for (let i = 0, len = arr.length; i < len; i++) {
    // do
}
const fn = username => {
    // do
}
function fn() {
    // do
}

const user = {
    name: 'xxx',
    age: 'xxx'
}
this.state = {
      username: ''
}
this.setState({
      username: 'yucihent'
})
结构赋值
this.state = {
    name: 'xxx',
    age: 'xxx'
}
const { name, age } = this.state;
属性名属性值相同简写
components: {
    Header,
    Footer
}
函数
methods: {
    delItem(index) {
        this.$emit('delItem', index)
    }
}
