1 定義一個變量
let a = 1,
b = 2,
tmp = '';
tmp = a;
a = b;
b = tmp;
2 算術(shù)運算
let a = 1,
b = 2;
a = a + b;
b = a - b;
a = a - b;
3 異或運算(會進(jìn)行二進(jìn)制轉(zhuǎn)換)
let a = 1,
b = 2;
a = a ^ b;
b = a ^ b;
a = a ^ b;
4 ES6語法
let a = 1,
b = 2;
[a, b] = [b, a];
5 數(shù)組特性轉(zhuǎn)換
let a = 1,
b = 2;
a = [a, b];
b = a[0];
a = a[1];
6 數(shù)組加運算符(優(yōu)先級)
let a = 1,
b = 2;
a = [b, b =a][0]
