**现有语言实现循环方式统计:**

    //1.for
    for (int i = 0 ; i < 10 ; i++) {
    }
    
    for (obj in array) {
    }
    // 2. while
    while(true) {
    }
    

**OC:**

    for (int i = 0; i < 10 ; i ++) {
    }
    for (obj in array) {
    }
    

### solidity:

    for (uint i = 0; i < 10; i ++) {
    
    }
    
    while (true) {
    }
    

### js

    for (var i=0;i<cars.length;i++)
    { 
        console.log(cars[i]);
    }
