/*初始化仓库*/
git init
/*添加文件到本地仓库*/
git add .(文件name)
/*添加文件描述信息*/
git commit -m "first commit"
/*链接远程仓库,创建主分支*/
git remote add origin + 远程仓库地址
/*把本地仓库的变化连接到远程仓库主分支*/
git pull origin master
/*把本地仓库的文件推送到远程仓库*/
git push -u origin master
从GitHub向本地down文件
git clone '代码仓库的SSH地址'

命令:
var let const
数组解构赋值:
let [a = 1] = [];
let [a, b, c] = [1, 2, 3];
let [a, b, c] = new Set([1, 2, 3]);
对象解构赋值:
let { log, sin, cos } = Math;
let { a, b } = { a: 1, b: 2 };
let x; ({ x } = { x: 1 });
字符串解构赋值
const [a, b, c] = '123';
let { length: len } = '123';
函数参数解构赋值
function func([x, y])
var f = v => v; 等同于 var f = function (v) { return v; };
(() => { console.log(1); })();
遍历 Map 结构
const items = new Map();
items.set(1, 2);
items.set(3, 4);
for (let [key, value] of items) { key + value } 或者 [[1, 2], [3, 4]].map(([a, b]) => a + b);
输入模块的指定方法
const { fn, func } = require("source-map");
字符的 Unicode 表示法
let txt = "u0061";
let txt = "u{0061}";
字符串的遍历器接口
(let i of text)
模板字符串,用反引号(`)标识
字符串中嵌入变量
let name = "micro";
var txt = `Name ${name}`
数据结构 Set
const s = new Set([1, 2, 3, 4, 4]);
const s = new Set();
[2, 3, 5, 4, 5, 2, 2].forEach(x => s.add(x));
for (let i of s)
Class 语法
class Func {
constructor() { }
add(x, y) {
return x + y;
}
get prop() {
return 0;
}
set prop(value) {
console.log(value);
}
}
let fn = new Func();
fn.add(1, 2)
let Func = new class {}
静态方法和属性
class Func {
static prop = 1;
static add(x, y) {
return x + y;
}
}
私有方法和私有属性
class Func {
add(x, y) {
fn.call(this, x, y);
}
}
function fn(x, y) { }
类继承静态方法
class Fn extends Func { }
Module 的语法
<script type="module"></script>
