js的基本语法
if 判断 语句 代码如下：
var pay = 1000;
var say = '';
if (pay >= 3000 && pay < 6000){
say = '还不错哦';
} else if(pay >= 6000){
say = '有钱人哦';
} else{
say = '给国家拖后腿了';
}
console.log(say);
三元判断结构:
say = ( pay >= 3000 )? '还可以哦':'给国家拖后腿了';
console.log(say);
switch判断语句：
switch (true) {
case pay >=3000 && pay < 6000: say = '还可以';
break;
case pay >6000 && pay < 10000: say = '有钱人哦';
break;
case pay > 10000 : say = '富二代吧';
break;
default:
say = '不好意思给国家拖后腿了';
}
console.log(say);
for循环语句：
var sum = 0 ;
for (var i = 0; i<10 ; i++){
sum = sum + i ;
}
console.log(sum);
while循环语句
var sum = 0 ;
var i = 0 ; //入口判断
while (i < 10){
sum = sum + i ;
i++;
}
console.log(sum);
